I just saw this a little while ago, too. There is also a
slashdot story.
It's funny because most will agree that submitting your site to Google using the existing "submit url" method doesn't do much good. The idea being that if you get enough links to your site (page) Google will find it. If there aren't enough quality links to your site (page) Google doesn't care about indexing it. This seems to go against that philosophy.
Most of my sites don't have any problem getting crawled, but I've got a wiki that doesn't get indexed too well because there isn't much structure to how the pages are linked throughout the site.
My host has Python 2.1, and their xml-sitemap generation script needs 2.2. I guess I'll need to figure out another way to automate it.
