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.

Cheers,
Lars
