What does the software or service do well? I use Slack to organize my small business group. Six small business owners and I meet once a month to support one another, strategize, and hold each other accountable in our individual businesses. We use Slack to help us organize our meetings and retreats, as well as share and archive resources and connect with one another between meetings. It's an amazingly intuitive software! I use the desktop version so I always have it running and get notifications when new comments are added. I could see this software used in so many workplace environments where there are multiple people involved in different projects. I used to be an elementary school teacher and would have loved to use it to share resources with fellow teachers as well as organize meetings and action items for specific committees.
What does the software or service not do well? The notifications are a little buggy. I used to get email notifications when my name was tagged in a conversation, but now they're very sporadic. There are two ways to see what's new in Slack--"new threads" tab and "bold" channels. I find that the channels usually show up as "bold" when there's something new to read, but the "new threads" is not always accurate, so I often miss new conversations.
What do you wish you had known about the software or service before using? I wish I knew more about threads. When you respond to a comment, you have to intentionally create a thread each time. If you forget, you will just create a new comment so it's harder to track the thread responses. I wish this feature was more intuitive each time so comments remain in the related thread.
