Google Reader just introduced functionality to create “bundles” of feeds. I subscribe to roughly 60 SQL Server blogs that I read on a regular basis. You can download an OPML file of these.
More interestingly you can just subscribe to the individual RSS feeds of these sites. If you subscribe to it in Google Reader it will create create a new tag labeled “SQL Server feeds” which is what I named my bundle. You will be subscribed to each of the individual feeds in my bundle. If you are already subscribed to one of the feeds it will just add this tag to the feed – you won’t be subscribed twice. I’m not sure how readers other than Google Reader will handle this.
