The site indexes external websites (like Google) such as blogs and personal pages, then finds links to media from these sites and gives the users searching links to these external files. In a nutshell, the site supplies media links to searchers.
Great color choice and everything there is nice, but what isn't there is the problem. Too much of the space on the site isn't use, maybe add some images or logo for the search engine somewhere on the site...
Awesome design, it works well too. Maybe make the ads more integrated into the site., they seam a bit out of place. For example the ones on the left side could go up to the top maybe? Or add some padding?
