I tried Zulip with the rust community and it completely ruined slacks “threads” for me.

Its the equivalent between a pot noodle and a steak dinner.

Zulip has a lot of other issues though, the app and on-boarding… but I really struggle to enjoy slack now.

teams, however, is a total dumpster fire for serious communication outside of video meetings and some minor ad-hoc 1:1 interactions.

Crashing constantly and being a resource hog killed Slack for me.

That and DMs being visible to whoever pays.

Teams, specifically on Mac and Linux, has been a shit-show of instability, weird one-off behavior, blank screens on start, login loops etc for my team. With how amazingly well Microsoft did with Visual Studio Code, it's a bummer how it seems that none of that expertise can be translated to other teams (in this case, the Teams one) as well...

Teams crashes my 5950x in video calls. Otherwise no issues but I can't claim to have used it much.

Discord is by far the best of the bunch combined with Jitsi.
