I recently found out about FreezeCrowd, and tried it out because to me, the most important part of social networks is posting and looking at photos. And I like FreezeCrowd! It's super photo-centric, and you can "freeze" photos and connect with people that way. It's also super user friendly and intuitive, which is great. I don't want to have to read a manual to use a fun site. It's also great that the members are all college students/alumni.
