I like the concept. The site itself was unusable for me in FF3.6/Linux. The site displayed after a bit of a wait loading, and then stalled my browser for 15 seconds or so before disappearing and leaving only a facebook like button at the top of the screen. It would be much better if you used plain html/css/js like other sites. One mistake I think you're making is that you're building the site as though it already has lots of users. This only makes it feel empty. For example, you have many post categories, which you borrowed from craigslist because you don't yet know what categories you'll need because you don't have enough posts. At this point all this does is segregate users from each other, when the whole point of the site is to connect them! Lose the categories. The site needs to seem as busy as possible to attract users. Just show all the posts. If a city has no posts, show posts from surrounding cities. Worry about categories when there are too many posts to sort through. Basically, keep it simple to start. There are so many parts to the site that I don't immediately know what I'm supposed to be doing. Don't worry about "sponsored posts", or "ads" or whatever else in a sidebar. Monetize later when you have users. For now you just have to focus on getting users.
