Talk about an overly dramatic headline, the "post that killed Bitcoins"? but the submitter isn't even sure if the arguments are valid? (And has hacker news turned into bitcoin news? it seems like there are several bitcoin links a day)
* Subject X is broached in an exciting blog post.
* The submission receives massive upvotes and hundreds of comments.
* Subject X simmers. Soon various HN link-targets (AVC, that Steve fellow, TechCrunch, the other guy here called Jacques) begin weighing in, netting their initial submitters still hundreds more karma.
* Before long, karma farming means that the front page is overrun with links to posts covering Subject X from every conceivable angle. "Why Subject X is the Future". "Why Subject X is a fad". "Launch a Subject X statup right now!". "Subject X is retarded, here's why".
* Then, one day, somebody posts about Subject Y.
