No, it's nothing fancy. It's just your standard Rails app. It saves a record for each word found along with time data, then runs queries grouping by word count and filtering between now and whatever time you choose. I'm sure that's a naive implementation and the app could certainly be optimized. I could open source it if you really want to take a look.
