Seconded. Rating TV episodes on IMDb is a very useful feature, especially now that it supports sorting episodes by rating, e.g., http://www.imdb.com/title/tt0098904/eprate?ref_=tt_eps_rhs_s...

This is the main feature that I use on IMDb. Rate stuff myself and explore based on rankings. Thus IMDb would be pretty much the last thing I would compare podcat to personally.

But please don't do x/10. Everybody's 10/point scale is totally different.
