I found myself just smiling whilst reading this. It seems DTube alone is getting ahead of quite a few cryptocurrency projects I could mention.

My only thought when reading about the nice additions you're making to content discovery is not to get too tied up in the structures made on steemit with the Hot and Trending page. My experience generally with using new steem apps is that I want an app that helps me find what I want, not one that just displays what steem stakeholders want to reward.
