If this already exists, I couldn't find it. If not, I would like to see some sort of (at least) an API so developers can create team websites or fan pages and whatnot. Maybe APIs for pulling user data, server uptime, ranked team stats, etc.
Maybe even make it a sign up type thing like the referral program and issue application keys so you can monitor who's pulling what info.
Just a miniature thought. This can surely be expanded on, and I hope some of you other players who know php, ruby, java, etc will back up this thought.
