I figure this is a pretty junk thread so I don't mind derailing slightly. Just wondering if you could briefly expound on the "centralized" issue.  I am much weaker in my deep knowledge of the Ethereum ecosystem than I am of Bitcoin.  My understanding is that they can not forcefully push code revisions to nodes.  But that Vitalik does have significant sway over the public opinion as a figure head, and therefore there is a socially centralized element.  Is there a formal "proof" of the underlying centralization/censorship, above and beyond social tendencies?

(For the record, I do have an issue with the DAO hard fork, I just don't know enough about the technical layout of their protocol to argue against them in an educated manner, which I would like to)
