Opinions on my site please

Was wondering if someone with experience in flipping wold take a look at my site and see what the chances are of it selling? I know these sites sell...in fact ive seen some bad looking ones sell, so I'm optimistic. I am unsure about the banner.

site is http://likesntweets.com

cheers

You need to tell details of monthly revenue, traffic and PR etc to have a estimate here.
