Boffin is a library for tracking hits to things in your Ruby application. Things can be IDs of records in a database, strings representing tags or topics, URLs of webpages, names of places, whatever you desire. Boffin is able to provide lists of those things based on most hits, least hits, it can even report on weighted combinations of different types of hits.
