This is a dashboard page, one of the templates Google provides. It allows you to create an iGoogle/Netvibes/Pageflakes type start page. Good for pulling in content from around the web, and you can embed Google Docs in here too.

For some reason it had trouble with the DavePress feed, which is odd as it is parsed through FeedBurner...owned by Google. Gah.

Oh, got it working now, using the CustomRSS widget.
