To be honest, the $work suite maybe good, but you cannot make money with it. You get $msftteamsfree of cost to your office 365 license. It is like Firefox which is better than Edge, but you cannot make money with it. Slack product is IMO a commodity.
I'm a teams user in my software service company. My managers say only because teams is free and because cisco webex is high traffic they are using teams, nothing more.. MOST of teams users are free . i dont see business joining MSFT just because of teams... Teams is average!!!!
Joe got a good snapshot through the CDC/@stake lens, but I would love to have an oral history of @JohnLaTwC and team inside MSFT, @daveaitel’s legal adventures, the Litchfields vs Oracle, Skylarov at the airport, Cisco vs Lynn at BH and the fallout, No More Free Bugs, etc...
