We've built http://twlisted.com and the app is up and working and the database is in very good shape, but we've been sidetracked onto other (paying) projects and don't have the bandwidth to give this the attention that it needs.
This is a machine driven directory of Twitter lists. Sort of like Listorious, except that there is no manual curation -- we don't edit the lists, we rank based upon user specified criteria. We've also implemented an API to query the list. There's a capability to purchase "sponsored" listings, but we haven't done anything with this. It's in PHP/MySql and is based upon qlWebDS Premium 5.1.0d_1DL, which we have *heavily* customized. There are several crawlers that go looking for lists via the Twitter API. We've done zero marketing of this and yet Google has indexed 1080+ pages. You might just be interested in the database, or you may actually know what you're doing and would be able to monetize something like this. Fred Wilson said that search and content would be one of the growth areas, so you'll be all set to be a player. If you're comfortable with PHP and MySQL you'll be able to take this over.
