This might be better on the XBMC forum, but figured I'd start here. What I'd like is a program that allows similar features compared to Netflix and Pandora's rating and recommendation systems. Are there any standalone applications (preferably for GNU/Linux) that do something along these lines? I've looked for XBMC plug-ins, and browsed the Ubuntu repositories, but there seems to be a distinct lack of a program or plug-in along these lines.
If I'm mistaken and someone can nudge me in the right direction I'd be appreciative, or maybe there really just is nothing like this out there either for technical reasons, or just lack of demand (maybe I'm just weird).
