as long as it doesn't look desperate (rather than going on eharmony for friends destination site, you'd give a service on your favorite socialnetwork/communities which proposes you //twitter"who to follow") ? For the "algorithm", why not partnering with Hunch a bit? Actually, it may be a good idea if it is an information site(rather interaction site not a match.com w/chat etc): people would just check which profiles around "could" become friends (based on near values/tastes/etc). It gives you an idea of who is around in your new town for instance. So that if you meet them IRL, you can say hello.
