Blockchains 101 feat. Ethereum second pass complete (new version pushed live but hidden).
Gentler introduction with database history and reasons to choose a blockchain.
Reorganized for more logical flow: General Blockchain -> Ethereum -> Smart Contracts -> Ethereum Networks
Pet Shop first pass complete up to testnet portion (new version pushed live but hidden).
To discuss tomorrow: I realized once I started with the deploying to Ropsten section that it could be a whole tutorial in itself, especially if we go through installing geth/Mist.
