What are some other examples of HN hating on an idea and then it turning out to be the next big thing?
I'd also have to disagree with your "everyone hated on Dropbox"; you can read the original thread at [1], many people said "wow, great!" That's actually the majority of the comments, and BrandonM's comments (which is what people usually refer to) is a lot more friendly and nuanced than "hating on the idea". After Drew's response, BrandonM's response can essentially be summarized as "right, I see how this would be useful".
Like I said: HN is lots of different people who disagree on essentially everything.
Is there any reason, 10 years after release, why I should be using Dropbox instead of my own network attached storage? Or does their product really just boil down to "storage as-a-service, as a service"?
