I've even noticed here on Steemit some of posts will say: Posted by a bot. Now wth is up with that? As far as people actually reading an article before voting I think you are right there. Speaking from experience I learned early in life not to put my stamp of approval on something until I read it. Live and learn.

Sometimes that laziness will come back to bite us as we've witnessed in the world of politics. (not sure how that would work here on this platform, but I still feel better reading a post and when warranted, even doing a bit more research, before voting on it.)
