The Pixies were on Austin City Limits last night. They rawked. But that's not the point of this entry.
I've been using a tivo for a couple of years now. It should know alot about what I like at this point. But it doesn't. TiVo's recommendation engine was instead deciding to record Saturday Night Live, which I almost never watch, save for when they feature I band I care about. Had TiVo consulted my other media habits, it would have put anything featuring the Pixies at the top of its priorities. Oh well, it's forgivable.
But TiVo is not my only means of consuming media. I also use iTunes and Democracy. Democracy is certainly less known than iTunes or TiVo but it sits right between them in terms of functionality. It is like an internet driven TiVo with an iTunes interface ( albeit an old version of iTunes ).
I don't have near the free time that I used to have, so maybe someone else will build an open source recommendation engine that looks at the music in your library, the shows you watch on tv and the net and then provides an opinion on content that informed by the totality of my likes as a web service for itunes, democracy and tivo to use to make these fuzzy decisions.
