Why don't more people post their startup ideas on HN?
jacquesm: It depends on whether people want to profit from their ideas themselves (usually people that have no capability to actually execute are in this mode) or whether you'd be happy to see the idea realized at all, no matter whether you had a hand in it or not.People that have ideas and are good at executing them usually have their hands full anyway, not much loss to them if they can get other people to run with their ideas. Also, they probably realize that their ideas are not all that unique.If all you've done in your life is get this one 'great' idea then you're going to be much more protective about it.And that probably kills the one chance you had at realizing it.
