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.
