He set this up so people could find friendly bars in their local areas for watching their favorite teams (primarily college). It all stems from him being and Oregon Duck and trying to find some place to watch the Duck's play in Seattle without getting bugged by enthusiastic Husky fans. Then he figured a lot of other people have similar problems when they move away after college, but want to see their home team while surrounded by fellow fans. Hence the site was born.
Anyway, if you enjoy college sports the site is worth checking out.
