It would be wrong if NateW hacked into and stole the source, or stole the design source/code of Dustin's project. But reproduction of someone else's work isn't ripping them off but is a compliment (it means that it's worth reproducing). As good as Dustin is, neither his ideas or implementation of his blog/cms platform are that unique.
