when we started our location based site launching soon :), we researched current and future competitors: key points we came out with: 1. Facebook absolutely will launch a friend finder (although they'll have privacy problems and they'll have to be careful) so most friend finders will get crushed. 2. most current sites are confusing- don't actually understand what they do within 10 to 30 seconds of looking at the site. Often they do too much that people care minimally about 3. Most location based sites have missed out on some very basic needs that people have. Many seem to be built by hard geeks for other hard geeks. Go out and talk to mainstream users, they just are like wtf? So dave has said what most people may have thought but were not willing to say because of what i think of as the 'twitter' effect'. Its the 'well, it could be another twitter, just that i don't get it yet' thought. However, the one advantage foursquare etc have got over some poor muppet like me with my $6,000 dollar savings invested in our idea is lots of money and an existing infrastructure. That said, these days, its amazing what you can do with $6,000.
