1) Tweeting out that I was playing a game so other people could join me
2) To post screenshots

Except it doesn’t appear you can tweet out automatically that you are playing a game. I want to be able to at ANY time go to the XBOX menu and have it tweet: “[GAMERTAG] is playing MW2 Team Deathmatch” or something like that. But you can’t. And there doesn’t seem to be a way to tweet out screenshots of things (like I manually do with my phone if I have a good MW2 run). My hope is that these features come later.

I wonder if MS got paid any more for this. That is the only thing that makes me think they are motivated to add this. I am sure there are some people who spend a ton of time on 360 that might use this, but IDK I agree it makes little sense.
