I think, we need some content insignificant mass appealing app, that can reward real participants. For example, a review app, that could take all amzon reviews out of amazon and reward the reviewers, who give better review ( in the form of curation).
They have that in @steemhunt, but it's often plagued with people saying stuff in comment section just to receive free votes from the dapp. And, I haven't really found anything worth reading there.
I know @knowledges has an entire tribe dedicated to that called Reality Hubs.
It's still on the Steem blockchain, but that frontend only displays product reviews. Ask him for more details.
Eh, I'm not sure. Can you make an app that lets you watch 3speak and or d.tube on Roku?
No, I can't.
Maybe... http://www.instanttvchannel.com/roku/quick ?
