Ask HN: Review my Startup

We just launched our startup, and it's currently in beta. The point of the site is to find friends based on what interests you have in common with them. Users will post about specific interests they have already selected. Your homepage consists of a mix of all your favorite interests. We also have a user directory where you can see who has the most interests in common with you, and what they've posted in which categories. We are using Facebook Connect for user authentication to avoid unnecessary account creation and inappropriate content. We are looking for people to help test the site out, and would like honest opinions on how everything works. We are very open to suggestions and ideas for the site.

Our site address is bunchify[dot]com. After clicking on "Login with Facebook" and accepting the permissions, use the invite code "bunchify-HackerNews".
