"Slack makes business communication easy, efficient and engaging"

Comments: I have enjoyed every bit of using slack, it gives me a feeling of using a robust yet state of the art communication platform. Hats off to the folks at slack, keep the good work going !!

Pros: It has carved a new segment in business communication and remote collaboration. Right now it is the gold standard as far as combining email and chat go. The User Interface is peppy and fun. The User Experience is very intuitive and efficient. We can edit messages that were sent without much noise. Love the slackbot as well it is very effective if used correctly. There are some really cool geeky features like Marvin etc which add the much needed spice to the remote work environment.

Cons: I haven't seen/used a native audio or video calling feature on slack, there are some advantages of having 3rd party video conferencing integration support but an inbuilt audio and video calling would have made this an absolute front runner in its segment. There should be a feature to notify when someone has logged in back to slack.

"Innovative Tool for Team Building!"

Comments: Overall I really enjoy slack! I prefer the desktop version over the web version. The desktop version allows quicker access! Also the direct message feature is important feature in slack that I use. Often at times sensitive message have to be share with an individual rather than the group. Also the emoji's are plentiful selection! I love the mass variety and options available!

Pros: The greatest thing I like about slack is the ability to create different channels to assist on different topics , groups, and teams within the organization! I also like the accessibility features! You can access Slack from virtually any device! I travel a lot and this feature is extremely important!

Cons: The software features can take some time to get use to if you have no computer experience. For me my biggest challenge was learning on how to use the alerts and notification features within the program. But in fairness I was able to grasp everything within a few days. So not that long at all.

"Slack is essentially advanced texting for business users"

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.

"A great collaboration and communication platform for teams - even young aged ones"

Comments: Coaching a team of 10-15 children from 12 to 15 can be quite challenging. However, we have been able to incorporate Slack in our day to day work. All of our communication is in Slack, independent of Facebook etc and the children had no problem with it. Great features, easy creation of subgroups and sharing. Overall great software and I probably one of the only options offering these kind of feature for free and so well integrated.

Pros: I love the easy creation of team channels for different topic, and the message threads. I honestly find it very difficult to use a platform without this feature any more. Not needing to spam the whole team with a smaller conversation is great, especially for younger teams. Also third party integrations is a feature I use all the time, mostly Google drive and simple poll for now.

Cons: Sometimes the notifications on my phone don't work very well and i occasionally have some complaints from third party apps (which has little to do with Slack though), like not being able to edit polls from simple poll etc.

"The best remote collaboration tool I have EVER used!"

Comments: Slack is the easiest collaboration tool I've ever used. I am currently acting as Scrum Master for four agile teams, and it's easy to keep in touch with all of them and coordinate standups. File sharing is extremely easy

Pros: Slack is a user-friendly, robust collaboration tool that allows for quick setup and access to channels both public and private. Asynchronous communication is a cinch and the Mentions and Reactions feature allows for easy access to what recent messages you have received.

Cons: Due to Slacks' third party app space, there are some features that might seem to be missing at first but need to be found as a third party feature. This involves an admin or an owner having to approve the app being installed. This can sometimes be a bit of a headache on the admin end, as it requires going to obscure parts of the app to approve. It could be an easier experience.

Alternatives Considered: Microsoft Teams

Reasons for Choosing Slack: Yammer was too slow and "social media" like for us. We wanted a faster, easier tool for us to quickly communicate with one another.

Switched From: Yammer

Reasons for Switching to Slack: Teams lacked a lot of the features Slack has, such as custom reactions, quick calls and file uploading. We decided to stick with Slack as it offered what a more agile-friendly experience.
