I've only been on Steem a few days and I don't understand most of the technical stuff, how the payments work etc, but I have to say I'm truly amazed that there was no mechanism in place to prevent people from upvoting posts they don't even read the day Steemit was launched. Of course, that could just be me and the non-techie world I live in, but in the world I live in, what gets done is what gets rewarded, so you make sure from the outset that what's rewarded is what you actually want to get done.

Very helpful post @sebastien - thanks.
