Atlo: But yeah, the aforementioned functionality to upvote is also vulnerable to abuse and should have been gone with just as as the downvote.
Yeah, but it is all but meaningless, so no harm to anyone, and no-one knows who upvoted.
Alas for the use of emoji, to make things clearer.
I also see it as a way to say you liked a post, without having to make a post of your own, so a quick reply if you like.
I've always seen downvoting as a negative thing, even for posts that deserved it. I've never felt that way about upvoting, though it can of course be abused. There is a positive aspect to upvoting despite any abuses.
In short, downvoting is disagreeing, and upvoting is agreeing.
In the end, it is what the community collectively make of it all, that counts the most.

And at the end of the day, we can still post and make our feelings known. So if someone does a post you dislike, then do a post to counter it. In a very real way, if others like your post by upvoting, then that can also be seen as downvoting the other post. But really, we don't see a count, so all pretty shallow, one way or the other.
