So, yeah. Was something that crossed my mind earlier. It isn't anything needed or important.
I think a perk to this would possibly help lessen useless posts and what not. Simply liking a post someone made shows you support it without causing an issue for spam.
Would probably think a thumbs up and thumbs down with the numbers would be better, and smaller too. But you catch my drift. Clicking the thumb would link you to who disliked or liked it. Similar to polls. And this could be for either all posts or just a thread OP.
EDIT: oh, well fuck. thanks for merging this, didn't know this was recently brought up.
