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.

What do you like best about Slack?

- Easy to use on a daily basis - Commands reminders and archive any post you want - Channel creation, chats and invitations are smooth to do - Calls, video sharing, voice notes are all improved and easy to use on the go - Integrations are amazing and easy to implement. we use Pendo, google, Gong, Chours and Jira. the possibilities are amazing - Plenty of customization options

What do you dislike about Slack?

- Recent UI Update is problematic. like a LOT.Mobile view is even worse with the new UI but its irrelevant here for now - Some new features are inconsistent, like notes in the top right corner. Sometimes it loads your notes, sometimes it does not - Searching. its soo detailed that it feels useless sometimes. the specific search filters that you need to type are not easy to use - Problems with message notifications with the recent UI update. like google integration chat it doesnt show up on the chat but it shows up on the activity counter

Communication, documentation, quick meetings, Integrations for seemles workflows are the top ones I can mention

"Slack 2024: Navigating the Future of Workplace Communication"
What do you like best about Slack?

Slack provides a central platform for team messaging, where you can create specific channels for various projects or topics, making it easier to track conversations and stay organized. It also allows for direct messaging for private conversations, supports file sharing directly in the chat, and offers powerful search functionality to quickly find past messages and documents. Additionally, Slack integrates seamlessly with a wide range of other tools, such as project management apps and calendars, enhancing overall workflow efficiency.

What do you dislike about Slack?

While Slack enhances team communication, its high message volume can be overwhelming, and managing notifications effectively can be challenging, especially for larger teams considering the cost of paid plans.

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

Slack addresses the challenges of scattered team communication by centralizing chats, files, and project updates in one place, which streamlines collaboration and reduces reliance on emails, thus enhancing overall team efficiency and productivity.

"A well designed application for companies"
What do you like best about Slack?

I have been using Slack for almost 2 years now. Slack made company communications easier and also very FUN! It is very customizable, you can add as many channels as you want and you can modify it to allow certain people access to it, you can lock the channel or make it public, and you can also edit it post-creation. Dead channel? No problem, you can archive it and it would still be viewable in case you hold some dear memories in that channel so it won't ever be deleted unless you want to do so. You can integrate "Apps" or as we call them "Bots" on Slack for Examble, you can integrate Coda as a bot which can make any Coda link sent in Slack viewable or "Previewable" before you click. In my company, we integrated ChatGPT and gave it access to our customer service tools so when you ask it any question, it will respond appropriately to the company's rules! We also have a Confluence integration, which notifies us if there are any updated pages or newly made pages which is extremely helpful in a customer service job. Slack is used by us every day, it is our only method of communication between us and managers during a shift which makes everything said by anyone "Documentable" which is very nice. Slack outdid themselves on the last update, they made it look really nice and almost like what Discord looks which is nice.

What do you dislike about Slack?

For 2 years, I haven't seen any issues using Slack or anything that I dislike to be honest.

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

It solves the issue of contacting higher-ups as they can be viewed and contacted on Slack. Also, it benefits us by enabling us to document every step we make during work so that word of mouth is no longer a problem!

"The easiest, fastest way to connect with colleagues and get answers!"
What do you like best about Slack?

It's much quicker and easier than email. I'm able to share information with individuals and teams, ask questions to large groups, and gain insights that inspire cross-collaboration.

What do you dislike about Slack?

Sometimes it's difficult to find what I am looking for in the search.

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

With our entire company spread across the globe in 12 countries, it is the one unifier for us. It helps create a melting pot that drives community. In addition, as a content writer, just scrolling the channels gives me ideas for content I would not otherwise have. Sometimes someone will post a question about our capabilities and someone else will respond with an answer and an example that I was previously unaware of — so it helps to break down silos.
