My thoughts exactly (about Filecoin and EOS.IO)
Nevertheless we have only Steem for now :)
For the last month, I was focusing on what is needed for DTube to be as performant now, as it could be if based on EOS.IO when it goes life.
My answer is infrastructure, with the can of worms that comes with it. ( business , legal, etc.)
Decentralized media is hard from a legal standpoint and we should have a solution if we want for DTube (or another service like it) to become mainstream.
