Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"The all around best collaborative communication platform"
What do you like best about Slack?

Slack was a great program before the pandemic, but over the last three years has matured tremendously into an all around collaborative communications platform that exceeds anything else on the market, including Microsoft Teams. Not only is it kingly powerful, but it's also fun! A rarity for a communication platform. It also boasts over 2000 integrations with other applications. And even for those applications that aren't represented, the third-party Zapier is a decent substitute.

What do you dislike about Slack?

Slacks development is uneven. Huge feature changes are promised, and years later they slowly disappear from mention on the company web page. They are forgotten about as if they were never teased. Slack is owned by Salesforce, which will not obstensibly a bad thing, it does run the risk of making Slack just another product instead of a flagship application.

What problems is Slack solving and how is that benefiting you?

Slack allows us to solve communication workflows in ways, Google Chat, and Microsoft Teams never could. The best feature is Huddles, which is a form of instant video meeting that anyone can join. No links are needed. Anyone can see who is involved in the video chat and even what the topic of the chat is.

"Slack the new era communication wizard"
What do you like best about Slack?

Slack is userfriendly, even the new user finds it easy to use. Creating private and public channels made easy, Notification schedule, even the user can alert someone who turned on the snoozed notification. There is an undo option available in slack, Ctrl+Z will unsend the message. Slack huddles and calls are good as well.

What do you dislike about Slack?

When someone gets invited, it asks for the domain, and most of them aren't aware of that. When we install the app and signing it redirect to the web and it takes lot of time and it requires multiple tries

What problems is Slack solving and how is that benefiting you?

Messaging the pears, team status updates, team channel, closed channels messaging, video conferences, and huddles. Communication made easier. Easy attachment of files. Integration with multiple apps like, salesforce, jira, lattice, google calendar, etc. Google calendar alerts are the one of the best one, it automatically changes the status as per my calendar.

What do you like best about Slack?

Desktop and app versions are both great.

What do you dislike about Slack?

Sometimes on the app it's hard to load pics or videos

Communicate to employees before coming to work if another employee is out, if traffic is bad and employees are stuck in it. It's nice to see those things before getting to the office so others are aware.

"Slack is efficient and easy to use"
What do you like best about Slack?

Easy setup, easy to use, and great features. This is a vital communication tool that is used within my office. I love how you can create new chats with specific people with a snap.

What do you dislike about Slack?

Honestly, there is not much I don't like about Slack, but I wish I had more control over the organization of my direct chats. I see the order rearranges based on chat activity. It would be great if I could have a separate section for "favorites" or have a bookmark feature that will stay in the order I placed it in at all times.

What problems is Slack solving and how is that benefiting you?

Several team members work remotely, only coming into the office 1-2 days per week. Slack allows everyone on our team to maintain communication to sustain our work flow and meet deadlines.

"Slack is a communications tool that just works!"
What do you like best about Slack?

As a programmer, it's a one-stop solution for all the development support. I can slack a coding question to someone that I work with, a community of developers (ie Drupal), or my university or personal group of colleagues. It quickens my debugging, you can share snippets of code. Also, you can just reach out to someone and talk. Since I started to work from home this is one of my favorite tools.

What do you dislike about Slack?

I think Slack should just stick to what it does best and not try to compete with Zoom or MS Teams. Also, it's a bummer that Messages and files older than 90 days are hidden.

What problems is Slack solving and how is that benefiting you?

Help Debugging issues. Check-in w/ other teammates. Share funny or stupid things. Search for threads for previous comments about a topic. Have Channels for a particular project or topic.

"The Ultimate Communication Hub for Teams!"
What do you like best about Slack?

Slack makes it easy to stay connected and up-to-date with your team. The platform offers many customization options, including personalized notifications, color-coded channels, and easy dragging and dropping files and images. The search function is fast and accurate, and the archive feature ensures that important information is never lost. Slack is an indispensable tool for any team looking to improve communication and productivity.

What do you dislike about Slack?

When you have a lot of channels or are part of a big company, the platform may look cluttered. It would be great if there were built-in project management features to avoid using third-party apps.

What problems is Slack solving and how is that benefiting you?

Slack plays a vital role in communication for our department. We work remotely, and the platform makes it easy to keep up to date with everything. The addition of huddles has been amazing!

"Having Slack as our digital HQ is awesome."
What do you like best about Slack?

Having a pulse on your organization is incredibly valuable and Slack is a great way to do this. I love how people in our organization, even though they're not always together, can communicate in a single place in a simple way.

What do you dislike about Slack?

When we started using Slack we didn't do too much training which created a plethora of messages and sometimes drowned out the important stuff. Once we taught about threads, pins, etc it became much more smooth.

What problems is Slack solving and how is that benefiting you?

Slack allows us to connect our business products in a simple way. When connected to our CRM it notifies our selected channels when a sale is made so that those who aren't in sales can share in the excitement! It's a great way to keep people on the same page and ensure excitement isn't limited to small silos of people.

"The best messaging tool for remote teams"
What do you like best about Slack?

I love how easily I can be in contact with my team and with anyone that is part of the company as well, and how it can easily be personalized to meet my needs and ad different integrations to make more interisting the day-to-day chat.

What do you dislike about Slack?

I don´t like how in brand new channels, the default option is not to receive notifications unless you are tagged, that have made me miss important information more than once.

What problems is Slack solving and how is that benefiting you?

It has helped me have a clear separation between work chats and personal chats without the need to be glued to my email inbox all the time to be in touch with coworkers or up to schedule with tasks

"Amazing and great communication"
What do you like best about Slack?

lack is great for organizing conversations via channels. Slack helps us stay connected to each other and our clients. Slack has many integrations to enhance the overall experience and make transitioning between various apps seamless.

What do you dislike about Slack?

One potential downside of Slack is that it can become overwhelming to use if there are a lot of channels and messages, making it difficult to keep track of important information. Additionally, it may not be suitable for huge teams or organizations due to its pricing structure, which can become expensive for larger groups.

What problems is Slack solving and how is that benefiting you?

o solve that, the company introduced Slack Connect, which allows you to set up shared channels with anyone outside of your organization. That's helpful, but setting up a channel isn't always the most efficient way to connect with a customer or client for a quick conversation about scheduling a presentation.

"Slack: Improving Team Communication and Collaboration"
What do you like best about Slack?

I really love using Slack for its user-friendly interface. It's so simple and intuitive to navigate and find the information I need. Another thing I really appreciate about Slack is the real-time messaging feature. It's so convenient to quickly communicate with my team members. Additionally, Slack integrates with so many other tools, making it easy for us to stay connected and organized. The search and organization tools are also fantastic; I can easily find the information and files I need. And to top it all off, Slack allows me to customize the platform to fit my specific needs and preferences. These are just a few of the many reasons why I love using Slack!

What do you dislike about Slack?

There are a few things about Slack that I'm not a big fan of. One issue is the occasional lag or slow performance, which can be frustrating. Another thing I dislike is the limited customization options for certain aspects of the platform, such as notifications. Additionally, the cost of certain advanced features or large teams can add up over time. These are just a few of the things that I find less appealing about Slack, but overall, I still think it's a great platform for team communication and collaboration.

What problems is Slack solving and how is that benefiting you?

Slack is solving the problem of poor communication and collaboration among team members in organizations. By providing a central hub for messaging, file sharing, and integration with other tools, Slack is making it easier for teams to stay connected and organized. As a user, I have definitely benefited from using Slack. It has reduced my reliance on email for communication with my team, and the real-time messaging feature allows me to quickly get answers to my questions. The integration with other tools has also made my work more efficient, as I can access all of the information and resources I need in one place. And with the powerful search and organization tools, I can easily find what I'm looking for. These are just a few of the ways that Slack has been beneficial for me and my team.

"If you need a virtual agenda on your phone with reminders included, Slack is for you"
What do you like best about Slack?

What I like the most is how easy it is to use, it allows you to create a space where you can add the corresponding people, for example I use it mainly for work, we created an office room where all the collaborators are added and we can add the information referring to any point that we are dealing with at that moment and it remains recorded for up to 3 months, it is very dynamic

What do you dislike about Slack?

What I don't like is that after 3 months the information is lost if you don't use the paid version, we use the free version and we create conversation threads so that the information or conversation that we need the most is kept a little longer. highlight or keep

What problems is Slack solving and how is that benefiting you?

I don't know what problems this application may have, I find it very useful personally, I have it on my phone and I use it as a personal reminder agenda, I put the date and time that I would like it to remind me of and it does, it would be great if in the pc could activate the notifications but for now it is very good

"Who needs email anymore?"
What do you like best about Slack?

Still learning about all of the great functions but really enjoy the "schedule send" option, the /zoom integration, the /remind function, and the ability to pin posts to channels for future reference.

What do you dislike about Slack?

Sometimes if I see a Slack on my phone and then go to look for it later on my laptop, I have trouble finding it if the person who sent the message included others. That is, sometimes I have difficulty finding the thread. I wish there was a "recent activity" feature.

What problems is Slack solving and how is that benefiting you?

The biggest problem Slack is solving is staying connected in realtime. It's great to have the ability to communicate quickly and efficiently with my colleagues (all of us are remote) without having to send an entire email.

"Tr slack once and never go back to other app."
What do you like best about Slack?

Slack has the best chat/message service for users around the globe. I used multiple apps which can be compared with slack, but slack defines the best of all. Slack gives the best functionality to huddle calls with anyone in our community anytime without interruption. The message feature with multiple sections like code snippets, clips etc., is best. Slack gives access to add multiple communities in it.

What do you dislike about Slack?

Not as such. As I said, slack covers all the sections for the user. One thing I could say is that slack sometimes gives slow responses, but that is negligible for anyone. Notifications are still showing even after viewing them.

What problems is Slack solving and how is that benefiting you?

Notifications are still showing even after viewing them. Filtration in the notification.

"A simple way to keep in touch with the team without sending emails that pile up"
What do you like best about Slack?

I love that we can simply DM someone without waiting crowding their inbox. I love that code blocks are (mostly) supported. It would be great if we could further use markdown to add a language and get syntax highlighted.

What do you dislike about Slack?

I can't think of much that needs improvement here. I do like that I can select what/when I want notifications for.

"Improved Communication Among our Employees"
What do you like best about Slack?

I like that Slack has a very user-friendly interface. It's easy to navigate, and the colors add a little fun to our day- to- day work tasks. I also like that the different rooms provide opportunities for employees to engage outside work-related topics. Features like Slack "huddles" make it easier to communicate with employees without having to jump around different applications.

What do you dislike about Slack?

I feel like the search tools on Slack need improvement. When trying to find previous conversations especially using keywords, the search results aren't optimal and requires extra digging/effort on my end to find the most relevant results.

What problems is Slack solving and how is that benefiting you?

Communication, definitely. It's a quick and easy way to reach out to employees without having to draft an e-mail. The message alerts and tag features make sure nothing is missed, and the channels encourage employee engagement. It's a great way to send company-wide announcements, and the GIFs allow us to make them more fun and personal. It's definitely the best way we are able to reach employees.
