Apple is now offering Knowledge Base articles via RSS newsfeeds. Grab your favorite RSS newsreader (NetNewsWire, SlashDock, etc) and head on over to syndic8.com for a list of all available Apple feeds.
[robg adds: These RSS feeds are a great way to keep current with all the updates in the Knowledge Base; I use the Daily Changes (the first one in the list) and the Top OS X Documents feeds quite often.]
