I actually already thought about it... I' ve had Home for a few days and I was going to create a S-3D club, but I found out it was 5$ at first... and at some point there might be a monthly fee or something.
Talking about Home.... it has great potential... it would be cool to watch live E3 conference or something else...
Still, don't like the Avatars... I really love Nintendo Miis instead
Xbox 360 avatars are nice too... Microsoft copied in a very good way
