Google Sitemaps

Not sure what to do this weekend? Brand new (launched just a few hours ago, still in beta) Google Sitemaps might be a good way to spend an hour or ten.

"Google Sitemaps is intended for all web site owners, from those with a single web page to companies with millions of ever-changing pages. If any of the following are true, then you may be especially interested in Google Sitemaps:

• You want Google to crawl more of your web pages.
• You want to be able to tell Google when content on your site changes.
