Not bad, but you should hire a good ui designer.. this all is a pain. Also, when I look at item summary (http://klipperapp.com/#item=2b6701a481a877ee59abc40cfb9f9f61) - there are no breaks and paragraphs.. Very hard to read.

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.
