alt Hacker NewsHeh, and rereading my comment, it comes across as more against the usage than I actually feel. It's not my personal style, and sometimes I find it annoying, but 80% of the time I think it's totally fine and expresses a nuance that would take a lot more words otherwise. Your usage here, for example, seems totally appropriate to me.
The reason why I was reticent to use it was not because I was uncomfortable asserting an absolute (the link showed clearly that mods didn't allow these comments, I don't see any controversy there), but more so that on this type of forum, the act of voting itself is the primary method of agreement. Saying "I agree" or "this is true" or "THIS!" is generally redundant and noisy.
I really like this conversation by the way. I'm actively trying to become a better writer (by doing copywork of my favourite writers), and no other forum on Earth has this sort of conversation in such an interesting, nuanced way.
