Nothing is said here that wasn't better said by Joel Spolsky over a decade ago: http://www.joelonsoftware.com/items/2005/01/27.html
Expected this to be the top comment. Nothing new DHH isn't widely praised for originality, but come on this whole article is like a total re-hash. And he doesn't even bother to mention Joel... to me that means he's trying to take credit, or he doesn't know about Joel... uh, yeah.
Unless you have more to say I think this is an unnecessary attack on David's person, especially that one might think of a couple of things he did that are original. ;)
