I'm a bit skeptical, since "commenting on HN" is so asymmetrical compared to sinking money into a startup in terms of how much you're invested, but I think it's an interesting experiment. I think if it goes right, with some iteration, it could help to pick out some interesting things.
Sure, but HN users aren't actually sinking any money here. They're just telling other people to. Which is maybe not so different from regular HN comments? Who knows. We shall see!
That's what I meant by 'asymmetry' - it's kind of the opposite of putting one's money where one's mouth is.
