I noticed this well thought-out post today from Chris Anderson at the Long Tail (which is a blog I've been meaning to read for some time now). It's on what Lego has done with their website, marketing campaign, demographics and mail order campaign to create a great two-way system of service for their customers.

Although Chris really likes the Death Star (which I have to admit is darn cool), I'm a fan of some of the historical Lego sets, like the Baron, here. Actually, everything in their sculpture category is pretty neat.
