A classic one is on the Dropbox 2007 launch post (https://news.ycombinator.com/item?id=9224).
In retrospect, some product ideas are dumb. Others are good. But because we see this kind of comment so often (really not trying to pick on you!), I wanted to point out that it might be a good habit for lots of people to notice if they are trying to describe a product by its list of features, and maybe think if that is the best way to achieve their goals.
Again, not trying to pick on you in particular, I think that habit is incredibly common for tech people in particular. And there's a lot positive to be said about that style of interaction.
