Reviews of Slack

The best team comunication tool
Comments: We use it daily to communicate, organize our work, coordinate activities, share important messages or company announcements.
Pros:
You can not only send direct messages to one or many team members, but you can also create communication channels for different topics. You can send gif and react to messages, you can share files, or even jump in a call.
Cons:
You can jump in a call it needed, but sometimes this feature doesn't work.

Work w/ Slack is better
Comments: It's a great platform to increase productivity and accountability while serving as the means of communications for our remote-only company
Pros:
The real-time features of being able to communicate effortlessly with teammates, co-workers
Cons:
Not much -- sometimes it doesn't sync directly from phone to computer or vice versa -- but that's user error, likely.
Alternatives Considered: Sococo and Google Meet
Reasons for Choosing Slack: Sococo offered more in terms of "office-feel" but with more integrations and features added to Slack as well as customer service -- it was an easy switch
Switched From: Sococo
Reasons for Switching to Slack: Slack has it all -- literally. Nothing more, nothing less than the others.

Nice ideas with issues
Comments: The idea of slack is great, and it helps my team communicate more quickly and effectively than something like Google Hangouts. However, with the introduction of Huddles, and seemingly with the purchase of Slack by Salesforce, there seems to be a lot more bugs than in previous versions of the sofware.
Pros:
Slack is very easy to keep in the background and to use on your mobile device. The best feature of slack is the ability for everyone on a call to draw on the presenter's screen without any setup. Its very easy to onboard a new user and have them communicating right away. The API makes Slack a great hub for reminders and system notifications.
Cons:
Over the past year or so, Slack seems to be getting a little buggy. There are regular problems with joining Huddles, getting kicked out of huddles for drawing when a presenter has drawing enabled, and getting audio to consistently work. My team has noticed problems on Windows and iOS.

Great for teams in multiple locations
Comments: Overall I really like slack and I admit now is the time to explore what else it can do. That being said, given how I use it I do feel confident in recommending slack for people who are looking for a way to communicate better with their team.
Pros:
love slack because it helps me communicate with my team better. We are all located in different parts of the world and I haven't met many of them. The message style function makes it feel lighter than email, and I feel connected. As a freelancer I also have multiple teams and channels on slack but they never get jumbled or mixed together, so that provides even more security.
Cons:
The downsides of slack in my opinion is that despite the search being great, it can be hard to keep track of everything that is going on in a large team, especially with multiple threads and streams, and you can easily miss something important. Thsi could be more of a company issue than a Slack one! Additionally, if you are not careful, Slack can become a huge time sink. Overall, though, I think the benefits of using Slack outweigh the drawbacks. If you are looking for a way to improve communication

Slack for Collaboration
Comments: We started using Slack as a way of communicating with each other and as a way of sharing materials easily. It does all those things and more and we love it.
Pros:
We use Slack for a number of things. We love that it has a very nice in house messaging system that keeps us all on the same page rather well. We use it's file sharing feature all the time as well. The channels make it easy to post relevant information to different topics and have real time collaborative feedback on those projects that are relevant to my team members who are on those projects without clogging up the inboxes of other team members who aren't.
Cons:
So far, we haven't found much that we don't like. It would be nice if there was a few more options, perhaps, that allowed for personalizing fonts or styles when writing to do lists or posts for yourself, but it isn't a major hangup.
Alternatives Considered: Workplace from Meta and Microsoft Teams
Reasons for Switching to Slack: We chose slack because it didn't require that we have a subscription to Microsoft (for Teams) and because it seemed a lot easier for our non-Facebook using staff to use (as opposed to Workplace).
