1. Half of the posts in my LinkedIn use words block chain - they are not coming from usual P&D crowd. I'm seeing lawyers post "Where are all the #ladies of #blockchain. So inspired by #blockchain diversity efforts!"
2. I cannot go to a restaurant/bar/cafe/coffee shop in NYC without hearing someone next to me talking about blockchain and awesome stuff they are going to do to be riiiich riiich rich on #blockchain. Yesterday, I overheard two Mormon kids on a mission talk about blockchain over lunch.
3. IBM's ads are all about blockchain.
4. And now Amazon is jumping into Blockchain-in-a-box
