Here’s one thing I like to do–

As soon as I realize “This is a person I’d like to group up with again”, I ask them if they’re in any Communities they really like, and would be open to having me join. I’ve ended up in a few interesting Communities as a result.

And Communities show up in the Social tab of your Blizzard Battlenet App (the launcher). Really convenient.
