Some functions of your site appear to be explicitly manual ("bubbling" polls into more general categories, linking congressional bills to news stories), but I was unable to find a clear breakdown of what is automatic and what require human intervention. That information is probably not important to end users, but as a techie I'd love to hear how it works. Would you mind providing a breakdown for the HN kids?

edit: you might also want to play with mod_rewrite; http://roger.dnsdojo.net/dev/udoa/index.php?module=home&... could be expressed as .../home/about or something else a little more human-friendly
