Brilliant looking site and I really like the integration with facebook & twitter. There are little touches that I think are really clever, like the general status of everybody on the site at that time. Its also made very clear how to use the site, however I don't think that there is enough to do to keep people using it.
just a suggestion: you can automatically determine user's location , not forcing them to enter the city/address. Don't want to advertise anything, but you can pm me and I can send you a link to the sdk you can use to get user's location via wi-fi. Or you can google it.
Site is very basic, but nice and simple, if you need any help in building Advanced Social Networking Sites lemme know i have alot of experience.
Before face-book was my-space before was friendster, I think anyone can take over the social networking world. I like the site, simple, clean, fun, definably get face-book connect and open connect and start marketing the hell out of it.
looks ok, search feature sucks. nothing found anything hardly. i searched for my first name and no results...really? my name is todd. c'mon. also, searched city, nothing. searched horny...nothing. only happy returned results. pretty bad. site looks good though...maybe it's just test data in there for now. good luck
