Teams is still woeful in both performance and features. Whilst you can easily drown in noise on slack, you are deafened by silence on teams. It is so difficult to discover channels and topics on Teams compared to slack, that I'm not sure there is a way to do it without being explicitly invited by an existing team member.

If you are using the mobile app then just lol. You'll always be seen as "away" even if actively engaging in discussions, and you'll be thinking you're caught in a time-trap with regards to accuracy of statuses and messages.

And my final rant is the pathetic conflation of "team" and "channel" nomenclature. The fuck is wrong with just calling them channels?
