I don't want to turn this into an OSMdoc thread. A few (sometimse technical) details can be found on the blog [1]. I've already implemented the history stuff and am in the process of importing the complete data. At the moment I take daily snapshots of the usage counts for each and every key and value. I believe daily shoud be enough but should there be a real need for even more fine grained data I could decrease the interval. This data would allow to see the tag distribution at any day in OSM's history and trend data could of course be derived from that but at the moment I do no further analysis on the data. That might change. Any feature requests are welcome but I'd suggest doing that in a different thread or via private mail.
