Can you cite those use cases?
We're using blockchain technology to build a decentralized cloud where users can store data on remote hosts without having to trust them, and without giving up ownership of the data.
The blockchain is a critical part of the infrastructure because the hosts need to be paid for the services they provide, but as untrusted entities we need assurances from them. Also, if you don't have a blockchain in the middle you need something like PayPal in the middle, which is a single point of failure.
But you are very incorrect if you believe that is the only topic of conversation. Perhaps using /r/Bitcoin is not a valid sample size.
In my day job, I'm neck deep in blockchain and cryptocurrency use cases - and there are conferences, webinars, real-world enterprise adoption, etc.
