Tonight was my first time playing 4e, and it was incredible. The funny thing is, I played this session entirely with people I've only met on Twitter, and the campaign started on Google Wave.

Wave is an interesting medium to RPG in, with some pros and cons. 

Pros:

-Everyone can type their background stories simultaneously, then you can read them during a lull in play or while you're waiting for the DM to set up.

-In my opinion, it is much easier to really role play when you can type! You don't have to make up a voice for your character, and you can differentiate between player and character dialog much easier than when you speak.

-Because you're already on a computer, it's easy to use online accessories to the game, like iPlay4e.appspot.com/ for your character sheet.

Cons:

-It's slow.
