In addition to the useful RSS feeds that have been listed on the SharePoint Community Portal Feeds list for many months now, the new (English only) RSS feed for SharePoint content on MSDN is now available at http://www.microsoft.com/feeds/msdn/en-us/sharepoint/rss.xml. If you're a developer doing work on SharePoint or just interested in SharePoint, you should definitely subscribe to this feed!
