Great for big projects

5.0 3 weeks ago New

Comments: Great, worked in a huge team, reaching out to the production and QA team, as well as having direct contact with all my middle managers at the company.

Pros:

I used Slack for my time being at a large company with 10,000+ employees. I had never been in a large team before but Slack made the project managment process and team comunication easy.

Cons:

As a user, none at all, but as a small business owner wanting to use Slack, it is quite expensive.

Best digital workplace you need for a small or medium company !

Comments: It’s part of our daily routine at work so I don't think we are getting rid of slack anytime soon.

Pros:

The instant messaging, the integration with API or other apps ( which in my point of view is very important ), the fact that you can use it as cloud docs management for your office are things that I mostly like.

Cons:

It can a bit frustrating finding docs, the search is not always responsive, but I can find my way around. The quality of the calls needs some work a little, but it's getting better, that's for sure.

Slack is essentially advanced texting for business users

3.0 4 years ago

Comments: I started using Slack because my client required it. I find that it cuts down on my email dependence but I'm often frustrated when attempting to compose a message without standard elements such as tables, inline images, etcetrera.

Pros:

I like the ability to stay in touch with our users via whatever device I'm currently using. For example, I can respond from my home computer, tablet, work computer or via my phone. I especially like the ability to be notified of a new message via my phone where I can read the message on the phone but can step over to my laptop to reply. I also appreciate the ability to add an email thread to a Slack Channel by simply adding a slack email address (each channel has a unique email address) to the CC field when I reply.

Cons:

The biggest con for me is the extremely limited amount of formatting available to Slack messages. I can make a font bold and add links to files/images but I really miss the rich text features many similar apps provide. It's also frustrating to need to keep typing adding the user name(s) when I'm responding to a message. I'm assuming that this is by design but it would really be nice to be able to "Reply All" to a conversation thread. The desktop Slack application (running on Windows 10 Pro) has a "clunky" feel to it. It's written with a framework that allows the Slack developers to write HTML and JavaScript code that is essentially compiled into a Windows application and it definitely shows. Something as simple as selecting text is counter-intuitive (until you realize that it's essentially a web page mascaraing as a Windows application.

Slack is a great tool for team collaboration

5.0 2 months ago New

Comments: I like using Slack for communication on my work projects and as a chat with my friends. Slack is a valuable tool for communication and collaboration in the workplace and everyday life.

Pros:

One of the main advantages of Slack is intuitive interface. Also I like a channel based structure which allows teams to create a dedicated space for projects.

Cons:

When working in a large team with multiple chats I did experience a message overload. It felt like constant stream of notifications and it takes some time to manage them.
