sasCommunity.org has started a page named SAS Community Planet. Visitors to this page will find a collection of weblog entries by members of the SAS community... a blog of blogs. NOTE: is included in the collection (of course!), and the collection is growing steadily.
You can subscribe to the Planet through an RSS or OPML feed, so you need never miss a post from any of your favourite sources of SAS knowledge. The Planet itself is created from the RSS feeds of the individual blogs.
The web page seems to show about one month's worth of posts, but it loads very snappily.
