It`s a simple and interesting site! But in my opionin you have to edit the color, the font and the position of the Site Name
Not bad, the content is pretty easy to read and I didn't feel overwhelmed by the ads. All in all I say good job. Not get yourself some backlinks to get your traffic and PR up
Its a very good concept and nice design of your site, i like the colors and images used by you , but you should use better logo for your site.
