In the world of Hai:
Another small note ... when I look at the "All" Teams view, I can see my posts. However, if I select one of my custom Teams, my posts do not show up. It was a bit disconcerting to write a post and then have my view jump back to my "HAI!" team view, and not see my own post.

Should your own posts show up in your Team views, or should they not? I can see a case for either situation, but I'm not a fan of having my posts show up in "All" but not in other Teams (and you can't add yourself to any Teams). Something to think about ...
Good point, yeah, I'll have to think about that. It should be consistent.

What do you all think? Should your posts show up in all your team streams, or none of them?
