Not bad, but you should hire a good ui designer.. this all is a pain.
Also, when I look at item summary (<a href="http://klipperapp.com/#item=2b6701a481a877ee59abc40cfb9f9f61" rel="nofollow">http://klipperapp.com/#item=2b6701a481a877ee59abc40cfb9f9f61</a>) - there are no breaks and paragraphs.. Very hard to read.<p>Other thing is speed. I guess that you're fetching feeds for every user request. You should think about caching and return precached results only or server will die with big amount of visitors.
