This is an efficient system but it detracts from the whole point of commenting. It should be to engage in discussion first and foremost, not simply to be rewarded for a comment that wasn't even read, and therefore didn't provide any real value. Yes I realise that a lot of Steemit is about social circles and loyalty of upvotes, but surely you shouldn't just automatically reward people. If Steemit is going to have a future this is exactly the kind of thing that will have to be avoided in my opinion
