HN and other sites have an 'I agree' button. Should that prove insufficient for expressing your enthusiasm for someone's comment, you can always find a grammatically correct way of saying "I agree", ranging from "I cannot more emphatically state my heartfelt support for your point of view!" to "FUCK YEAH!". "This." has always just seemed like a meme for the terminally grammar deficient.

Wow. What is wrong with "you people". Hacker News has turned into a really bad episode of the Player Hater's Ball. I used the word "THIS". As much as I actually like the term, how exactly does that make one "terminally grammar deficient"? Good to know that we can forget about the middle east for a while and focus on problems with THIS. Just let it go, man.

Life will be SO much easier for you if you just let shit that really doesn't matter go.

Read it, react. If you REALLY can't control that reaction and THIS just REALLY grinds your gears... go ahead and comment. I don't want your next aneurysm on my conscience. Maybe think about controlling what annoys you a bit. They have really good articles online for this kind of stuff -- lots of people are dealing with it. You are not alone. YOU ARE NOT ALONE.

Technically the upvote/downvote aren't for agreeing and disagreeing, they're for curating the content to stay on-topic.

But in practice everyone uses them as agree/disagree.
