Interesting approach to populating databases with sanitized data. It's a perennial problem in development and test and I like this idea a lot more than taking a production database and scrubbing it of confidential data.

I've been using bayesian filters in google reader for a while. they work fine for something like reddit, (actually the more it filters the better). Most of those titles are under 140 chars. So I'm betting this would work fine. Personally I just unfollow though ...
