For those of you who haven't seen it, take a look at Domas' Mituzas wiki-stats:
This is real, accurate hourly snapshot data on the access to Wikipedia
captured from the Wikimedia Squid servers. Project counts show the
total access in a time period to the different language editions.
This is great stuff for visualization, behavioral pattern analysis,
and other purposes. If you do something with it, let us know. :-)
URL may change in the future - we'll put a redirect on the above one
if that happens.
