Speaking of visualization, I started looking into techniques for visualizing blog archives yesterday. While you can compress the month links into a table, something that presents some post-wise salience would be good.
The only thing I really found searching (your blog archives should never, ever, ever have “blog archive” in the HTML title, please) was this research paper (here's a PDF of the paper) describing a display the investigators implemented as a Windows application.
While this would translate okay into an interactive HTML5 archive view, surely there's something better/cleaner/more explicable. Anybody got any pointers?
