Ecosystem: History Statistics

For the past two weeks, the has been accumulating historical data on every weblog’s rank and inbound link count. I’ve just now implemented the front-end code to show this information on the details page.
So: You can now see how a weblog has moved up or down in the Ecosystem over time.
I am planning to keep a decent chunk of this information online (past month, perhaps?) and archive the rest for posterity. Perhaps someday somebody will want to do research on this kind of thing; if so, I’ll have oodles of data for them.
Spiffy graphs are on the agenda, but I have thus far lost my argument with the graphing package I’m trying to use… perhaps next weekend…
