Thanks Travis. It seems that a visual re-design will be in my near future. A ranking system is a great idea. The idea behind the posts separation is that you can search according to the city you are in. I guess that a short paragraph at the top of the homepage or an about page would be a good addition.

Quick question. From a user standpoint, is creating an account more annoying than filling out a captcha everytime you want to post? Or should I find a way to avoid both?
