To me the word you quoted is much stronger than "exactly" or "I agree." The latter two are about the sentiment but the former means something like "This is the best possible phrasing I can imagine: I completely agree and you have captured everything, perfectly." While for a deep discourse (as on HN) -- Oh. Okay so nevermind. When I started to write this comment I was going to say that here on hacker news it fosters a deeper discourse, but as a poor reader on Reddit reading through 700 comments, do you really want to read the long sentence I just quoted, or are you helped by reading "this", to call your attention upthread. However I realized that Reddit's 700 comments on each thread are - almost all noise. "This" is a kneejerk one word answer that completely shuts down discourse. So after actually writing my comment I have switched my opinion. Which itself may well have been due to the style of discourse encouraged here!
