There is a lot of good stuff about lean on the Internet. Some of my favourites are:

Gemba Panta Rei: This is hosted by Gemba Research, a Washington DC based consulting company. Jon Miller, the main contributor, has a lot of insightful and interesting posts. For example the latest blog post is about how Dwight D Eisenhower could be seen as a lean thinker

Lean blog is written mainly by Mark Graban. It has a lot of good stuff, much of it related to Lean Healthcare, which is Mr. Grabans main interest. It also hosts a podcast service: lean blog podcast with interviews with leading lean thinkers to put on your MP3 player. For instance in episode #43 you can hear a wonderful impersonation of Dr. Deming, telling why Six Sigma is not in line with his philosphy.

The Elegant Solution, by the author of the book of the same name is a well-written blog about lean and Toyota. See for instance this post about A3 -thinking
