Would be nice to be able to filter like "show me an API for TV show data that uses JSON and has a free option". Would also like a curated list of client libraries (there are like 2000 Twitter API Ruby gems - which one is the best/most active/most supported). I've used http://www.programmableweb.com/apis http://www.programmableweb.com/apis in the past, but the data seems kind of stale.
