Nice site, the content i mean, but very boring theme. Change the default wordpress theme to something that goes with the content of your site
The design looks too plain.. you need a customized header. Also.. for your first ad unit, it kind of sticks out of the layout, use a 1/2 banner ad or block ad instead.
Theme no way change it lol...its to old and plain.. try a unique one..Yeah iagree add a custom header also.. - Regards
