To subscribe to blogs you first need to set up a news reader as described on SubscribeToChanges. Then, attached to this page is an "OPML" file called BlogFeeds.opml. Almost every blog's news feed is contained in that file. If you import this file into your news reader then you will be subscribed to everything in the file. This is a fast way to set up multiple subscriptions.
There are a couple feeds missing from the OPML file. You will have to subscribe to them manually. They could not be put into the file because the feeds are password-protected.
