Exactly, as @apshamilton said: "I can't post my blog on Bitcoin."
Bitcoin's goal is to be digital gold. But digital gold doesn't mean anything inside of this same game where the bankers & governments control all the currencies and internet connections...
Blockchain tech is drastically more important than being a new shiny quarter. But that's not because of BTC, it's because of things like Steem, Ethereum, LBRY, etc.
