I guess I'm the only one...
Good. I like Teams more than Skype and get annoyed when people send me Skype IMs at this point. Not because I'm particularly fond to Teams so much as Skype performs terribly in my org. Teams does a much better job when it comes to meetings with more than a handful of participants and on mobile in general. Sharing images over chat works much better also. I mean for legitimate work purposes like screen clips, but the unfortunate side-effect is it also makes it easier for people to share stupid GIFs.
