This is how it goes when I post a comment on Gawker.
Me: Reasonable Brilliant Comment.
Commenter 1: Response including Known Fact, which I already know but should have stated in Reasonable Comment. Known Fact is not needed to understand Reasonable Brilliant Comment.
Commenter 2: Same Known Fact
Commenter 3: Same Known Fact
Commenter 4: Same Known Fact
Commenters 5 - 27: Same Known Fact
Commenter 28: Completely Wrong Information.
Me: That information is wrong because Reasons.
Commenter 29: Some Generalization About Teh Libruls
Commenters 30 - 34: Same Known Fact
Commenter 28 again: Double down on completely wrong information, insult. Post link or quote that does not actually help his argument.
Me: Refute argument again, ignore him from here on out.
Commenters 35 - 37: Same Known Fact.
Then some time will pass. Maybe about 12 hours.
Commenter 38: Sexist ad hominem for no reason.
Commenter 39: Same Known Fact.
Commenter 28: OH NOW YOU’RE NOT EVEN GOING TO RESPOND TO ME BECAUSE YOU KNOW I’M RIGHT
Commenter 40: Same Known Fact.
Commenter 41: Person sympathizing with me for what an idiot everyone is.
One week passes. Article probably gets linked in an update article.
Commenter 42: Same Known Fact
Commenter 43: Same Known Fact
Commenter 45: Insult about Teh Libruls
Months pass. Assuming the article gets linked again.
Commenter 46: Sexist comment.
And that is the lifespan of a leading comment on Gawker. This is an aggregate of many years experience commenting over there, not based on any one conversation.
