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.

"best application for corporate interactions"
What do you like best about Slack?

The real-time messaging feature is a game-changer. Communication is instant, and the ability to create different channels for specific projects or topics ensures that discussions remain organized and accessible.

What do you dislike about Slack?

one common complaint is the potential for notification overload, especially in larger teams or busy channels. Users may find it challenging to manage and customize notifications effectively, leading to distraction and reduced focus.

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

easy to navigate. Setting up channels, direct messages, and integrations is a breeze, making it a user-friendly platform for both new and experienced users.

"Best communication platform for any team size"
What do you like best about Slack?

The most helpful thing I find about Slack is its integrations with a lot of other platforms. In my company, we had multiple integrations with slack, like asana, donut, small improvements, and what not. It makes it very very easy to track the notifications via slack as it makes the communication very quick when you're working.

What do you dislike about Slack?

I don't find any major downsides for slack but I do believe there's some room of improvement for the notifications part. Sometimes I do miss some texts on the channel because of too many texts and slack doesn't give continuous notifications.

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

We use slack for quick communications within the teams, or with individual teammates. Slack here helps a lot when there's a need to communicate urgent information to a larger audience with the help of channels, literally in seconds, no matter in what time zone the employees are.

"The best way to communicate with colleagues and clients"
What do you like best about Slack?

The option to join multiple Slack spaces/organisations, using it both as a work communication, and networking tool

What do you dislike about Slack?

The inability to schedule recurring statuses

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

The need for fast communication with colleagues via text, video and voicenote. It offers super easy file uploads that I missed hugely having worked at an organisation that leveraged Teams for internal messaging.

Frankly, Slack is the only tool that has worked wonders for me since deployment because all processes run smoothly without hitches.
