It does seem like the XB1 threads have a lot of posters with Sony related avatars and sigs. but I think that is because of the lopsided ratio of MS fans to Sony fans here. I also have no idea how bad or good the Sony forums are because I VERY rarely open a thread from there.
Being in the minority is part of life here as a MS fan. Thicken up your skin, take the high road and try not to respond to what you consider to be circle jerking, it's easy to ignore. If you REALLY don't like it then bounce but I have a feeling that wherever you go on the webz, you'll be greeted by the skin slapping sounds of the circle.
I LOVE paying for Xbox Live! I also love that my love for it pisses off so many people.
