That's true. Facebook and Steemit are really very different in the grand scheme of things. Steemit is more like reddit than anything else. I was simply comparing how content providers are being rewarded for the sake of this video.
But the reason I think APPICs will be a success is the fact that they're being built with the SMT provided by Steem. Even if they got no outside exposure, they would still be a success just from all the Steem users who will be flocking over to their platform. Steemit was basically the test model for the SMTs and because it's been so successful, more platforms are looking to take advantage of Steemit's proven technology.
And I'm not sure about dock.io. That's the first I've heard of it. There are a TON of projects being built on blockchain technology, and like you, I'm not as interested in the ones that I wouldn't personally use. But there are some that I wouldn't use that I still do invest in. Voise is one of them. I'm not a music creator but I can see the power of setting up a blockchain-based music platform that allows artists to earn 100% revenue. That's just one example. Of course there are other projects that are just completely far-fetched, or even worse, projects that have ZERO plans for anything.
