I like the idea of "NrMe" -- a place where users on the iPhone can chat based on location. Specifically, NrMe shows posts within a certain 9 block geo location. The idea, in theory at least, is that you can get information about clubs, bars etc... from people at those specific locations.
In practice, despite an initial positive review from TechCrunch, NrMe is essentially a ghost town. I can see exactly 4 posts from my location in central Santa Monica, and the last one dates from 6 days ago.
The app is also, unfortunately extremely ugly. The choice of color and graphics feels very 3rd grade. Avoid this one.
