I think this is a great post. I do wish it covered some of the other Bitcoin 2.0 concepts since it can do more then just efficiently moving small amounts of value around. Many think that concepts like smart contracts and fractual ownership (e.g. Reddit's recent announcement) require new altcoins, metacoins, or ethereum but don't realize Bitcoin can natively supports them too. There are already open source colored coin [1] APIs that allow anyone to model ownership of anything on the Bitcoin Blockchain, without any intermediary currency.
