I would like to put forward a suggestion that you open a facebook page for SI. I am sure this has been discussed before but I would just like to put forward my support for the idea.
I think it will make the members of this website more active. I know you already run a Twitter account that updates every time you post a new news item but I think FB will allow users to ask questions and get answers easier, get clans together for online games (End of Nations, BF3, MW3, etc) and advertise the website more.
Obviously I know it will be a bit more work but believe it will most certainly bring benefits. Even if its only for members to game more together.
