At the risk of being off-topic, I hate the fact that many modern entrepreneurs use the hilarious-in-hindsight comments on Dropbox's Show HN as an example on why startups should ignore criticism to be successful. Dropbox is the exception, not the rule. (Additionally, the demographics of HN today in 2016 are much, much different and more technically diverse than in 2007, so the irony would be less likely to be repeated)
