great idea behind your network. it would be much more lovelier if there is a more user friendly navigation on all the pages. Also possibly if you can get a better performing hosting service.

Also when you get on the events page or places, the Login on top of the site goes straight to twitter oauth, this will make it difficult for people who want to use your facebook connect if they get a link that takes them straight to the other pages and not the home.

Good luck with your endeavors.
