Well, this was.... something.

A lot of that does make sense... many people with high reputations have been upvoted a lot in order to get those high reputations and have continued to stay invested in the system.

Then there are witnesses and the techy guys that earn a lot of stake through other means that doesn't include posting or commenting a lot.

Then there's everyone else... and then the crazy accounts.
It does reinforce the theory that the best way to earn Steem is to have powerful people like you... which really also applies to every other type of currency.
