Ben and I attended the Ethereum meetup earlier this evening. Was a great group of people (around 10) held at Sidewinder Bar. Many topics were discussed, with the word decentralized/decentralization used at least once a sentence for hours. Kent had a brief presentation, the most personally notable part of which was how to monetize open source decentralized applications.
