I'm quite happy to see a lot of alternatives to YouTube popping up. You have now have PewTube, BitChute, the now defunct Vidme, and now DTube. I hope that people would stop using the word 'tube though. Because it makes it sound like a copycat of YouTube.
I'll definitely signup for DTube! I like the idea of websites built over the blockchain. This is definitely an improvement. And there's of course a monetary incentive doing so.
