As a newcomer, I'll be honest, it is a little strange. Most of the other forums and gaming sites I've frequented online have been dominated by the 360 crowd. There are places where most threads about anything Sony will have two snide comments to every positive comment.
Also, and I mean this without malice, there is usually less for Microsoft fans to talk about exclusively amongst themselves for most of the year. Microsoft goes all-out in fall and early winter but doesn't give a lot of love to the rest of the calendar. And, of course, not having a hand-held adds to the discrepancy in available subject matter.
I see no reason to change anything, though. There are TONS of places where it's tough to be anything but a 360 fan. Being atypical isn't a bad thing.
