The average gamer being younger on XBL doesn't help either I guess... It's really a shame, those people should get more bans.
I know the last thing I want to hear when I go back from work and decide to play a bit is a 12 year old retarded kid screaming homophobic insults in my ears...
That's why I actually prefer PS3 are sold WITHOUT headsets... It's kind of an IQ test, you gotta go and buy a headset to be allowed to talk on PSN. ;)
