I think Microsoft is basically giving teams away because it’s such a piece of Shiite. Our school district is using it and everyone hates it. Hard to compete with free though

I find Teams far more effective than Slack.

School districts will almost certainly hate everything they were forced to start using over the last few months because their entire workflow has changed dramatically. From top to bottom and they’re having to invent new things on the fly. They will almost certainly get stuff wrong.

Normally, such a radical change would have involved months if not years of planning, followed by months of trials, before even being deployed in 1 class for 1 subject.

In contrast, most of the medical workers I know use Teams for telehealth...and they love it.

It's a better app than Google Whatever (Hangouts? Meet? Duo???) and Cisco WebEx, though Zoom is much easier to use for larger meetings.

I think Teams is my favorite video app, but I find it lacking in persistent chat.

My org uses Teams and I’m now a member of probably 30 teams with lots of channels each. I ignore them all as there’s too many.

Slack is different because I just join specific communities.

Also text search is bad right now in Teams, but is handy in Slack.

Why are Twilio's competitors not doing so well?

It's less about that and more that Slack has to compete with free. Twilio does not.

Slack was free before Teams was free. They thought they had won the war before the first battle took place. Slack could have been Zoom, but instead it was just a pretty web client to IRC
