Lady Gaga has created her own social networking site called Little Monsters. It's built around Gaga's fanbase and is in invite-only beta testing mode right now.
The site looks similar to Pinterest, which lets users drop pins on locations and things they like. It also uses elements of the Reddit site by letting fans rate cool content that they like.
Little Monsters will focus on fans sharing and creating photos and videos and letting users hype up content that they are into.
