On the other hand, I only hear about the feature as a product or network effect startups here on HN. Around town, folks I interact with and companies I all work with have real products and at least a real revenue source.
It's like going to comic-con and deciding the rest of the world dresses like that.
It is a bit the same with me and programming/developing. Revenue is my new metric for how well I am doing. It makes it harder - yes I can come up with a solution, but can I do it in a short time, suppressing my perfectionism (come on - we all have it), and in a responsive enough manner to get people to pay for my work? It is just taking it to the next level.
And I do rather like money.
