Literally every feature you mentioned as a benefit of XBLA is available on Steam. And i can access Facebook and Twitter on my PC and my phone, without having to pay $60.
and one of your complaints about PSN was that not everyone has a headset.... how is that the networks fault? The capability is there. Imsure there are millions of XBLA users who dont use a headset, and there are also millions of XBLA users who are annoying moany idiots who chat constantly on their headset. $60 for that? No thankyou!
