Lately, xbox live has been really buggy, especially when I play COD4. Sometimes my ranking and gamertag don't show up in the interface at all. I've also had trouble with bugs in other games. But the biggest problem is bugs with the new interface. I can't believe that Microsoft would have a new interface for so long without working out any bugs. So this is just my little rant, of course Microsoft wouldn't pay it any mind at all, but they should.
