Re: vast majority of trollish twits are not that clever
"clever" is a very vague word. I would argue, that some (many?) world-known figure trolls that appear on twitter, are "clever", as otherwise, they wouldn't have become world-known. Even if you define "clever" as "intelligent", the same argument applies. You need some (special traits of) intelligence to have got to reach the very top, in politics or business, say. Even if you were to claim that getting to those tops requires a long and sustained path of backstabbing and bribery (combined with lack of empathy), this still requires certain, above the average, level of cleverness / intelligence to perfect the art of backstabbing and bribery, lack of morals itself is not enough, methinks.
