Upvoted and resteemed for good analysis.
I think vote buying is bad for the steem economy and I would be considering dedicating my SP toward suppresing it. Right now it's it's a cool gambling experiment but I hope in the future some level of oversight is being exercised by the people selling their vote.
It would be interesting if you could come up with an article on the cost of reaching a level of exposure on Steem.
For example ratio of steem needed to be vested vs steem earned by an upvote. Some cool data could also be extracted from the numbers of views earned by a top trending post vs lower voting. So basically a distribution graph of rshares vs views on steemit.com.
