I just discovered this article by Garrett Gitchell on his Horizontal Change blog. It mentions an article I’ve written a while back and provides a set of highly relevant comments in reaction.
The site provides good, concise and wonderfully opinionated (I should recognize opinionated when I see it, right) writing on consulting and other interesting topics. An excellent read if you have the chance, but be warned, there are quite a few blog posts there that will get you thinking.
