Very interesting and pretty amazing. I keep reading about blockchain scalability issues outside of Steemit, though, so how will FOAM, and whatever games/apps that get built on top of it affect the Ethereum blockchain?
I think I might have read it has one of the more versatile blockchains out there but still, this kind of thing has the potential to explode if the Pokémon Go phenomenon and now the CryptoKitties craze are any indication.
I agree with you about places like coffee shops getting in on this, however, businesses need to know, first of all, that these things are even possible and then figure out profitable ways to participate in building them out so they can potentially reap the rewards.
In our area, the majority of the Pokémon stops were in small boutique shops in the older downtown section. I don't think any of them really knew why more people were wandering around with their phones out, so I think they've missed a golden opportunity, since most of the hype has died down.
The gamification is a few years out, but I think tech savvy business owners (or consultants) will jump on the train early and get some free press if they pay attention. "Local Business lures in customers with free cryptocurrency, news at 11!"
Scalability is the make it or break it of the Ethereum blockchain, but the cool thing is that there are a number of current solutions being worked on by multiple teams.
