Very neat breakdown, David! I think the more big players share their experiences with Steemit & Dtube on the centralized, albeit bigger platforms, the more users will see the massive benefits of adopting it and cutting out the greedy middleman.
As you mentioned, there definitely is still a way to go until all the issues are resolved, but I feel that the Steem platforms have already started off on a better foot than, for eg., Youtube has when they started. And knowing how much they've grown, it gets very exciting to imagine the incredible potential ahead.
Go David! Go Steem!
