This was a pleasure to read. Ultimately the "golden source" for how Steemit works is, of course, the source code itself. I don't have time to analyze the code myself, so it's great to see posts like this taking a look at it. You've got yourself a new follower!

I'm a bit disappointed the change was postponed, was looking forward to seeing how it would work in practice. But oh well, debate and careful consideration of changes is a good thing (as long as you don't get deadlocked forever like the Bitcoin block size craziness).
