i disagree, it's a great functionality that people should learn.. and here's the simple point.. you can BOOST a comment you disagree with, so that your argument AGAINST the comment will get more visibility.. reddit is dysfunctional, and this mechanism can help fix one of the problems reddit cannot get rid of.. this mechanism can help discussion, and fight against things like brigading..

think about it a minute.. someone makes a really TERRIBLE point that you can dismantle easily.. tear it down, and BOOST the hell out of it.. reddit cannot accommodate that.. keeping those two functions separate is critical..

this will help keep every thread from becoming a popularity contest that is entirely predictable, once people figure it out

edit to add: i've only been using this platform for a few days.. but i promise you, it works the way it's supposed to.. try it out..
