So many developers these days fall in love with the decentralization ethos of Bitcoin and then what do they do? They go out and start a state-registered company and build a centralized software service that makes use somehow of the Bitcoin blockchain. Everybody trots out Mt. Gox as a cautionary example at this point in the discussion, so I may as well pile on.

Of course both of those approaches are perfectly reasonable and likely appropriate depending on the business niche, but the point is we need to look at all angles of a problem and work towards decentralizing them to find better solutions, if they can be made cost effective.
