I wasn't planning on linking to anything involving SXSW this week since every going-on there will be blogged and tweeted to death without me, but I liked the premise of this: Three dev teams were tasked with producing a website to uniform design, content and technical specifications within 100 hours, each in a different CMS: Drupal, Joomla or WordPress. My friend Tom Boutell provides session notes (and better backgrounding than the Showdown site provides).

Ultimately, the result is not a proof of any platform's superiority, but that there's sufficient functional overlap of the low and high end CMSes to make specifying a platform a considerably less nervewracking experience than it was a couple years ago.

Incidentally, Tom just announced Context at SXSW today, a brand new CMS based on the Symfony framework.
