I'm kinda agin 'em. I do not value the opinion of a bot. I may value the opinion of a person. Regardless of my disdain for the opinions of bots, those opinions devalue my opinions by competing with me, and with other people too.
Bots may have uses, but competing with humans in valuing content is not an appropriate one, imho. Dunno how this might be achieved (I am not a coder), but I reckon it oughta be.
