You've certainly thought it out well.
Just one point: any content-driven start-up expects to grow into a paying company via advertising revenue. As per the standard model, there'd have to be a split of the ad revenue: some to us and some to Steem Inc.
Yes I do expect that and just didn't include that in this post as I wanted to focus on that upvote bidding idea. I did include the fact that the revenue would be split the last time I wrote about advertising but I just didn't want to complicate this post too much.
