There are a few people doing different variations on Steemit although it's not perfectly build for it. (see @lordnigel and @o07 for a few different ones). It's probably not quite what you had in mind although since you can see the everyones wallet you can see that prizes are/aren't awarded.

I like your youtube channel. I think you might get some good traction on here with dtube once you get some followers. At current steem vs sbd prices you probably want to set your posts to 50/50 rather than 100% steem too.
