Great colours and well built design! A few things I would change are: - The dropdown from your menu is too much grey, maybe use a different colour for every dropdown? - The bottom of the design is very nice with its colours, maybe it's possible to do a little more of these colours on top as well. - Spice up the main menu a little.
Nice and clean design. Colors are good. I may change the ad colors : your other links on your page (main menu, tags,...) are green, so I would put the ad title green, and the ad text black. Just my opinon, but if your CTR is good, don't change anything, it is well blended.
i love sites like this, web2.0 is the way forward, not sure about the name, hyphens let sites down alot!
