1) I have encouraged question's author to do that anyway even if there will be no profit because that has indirect positive effect;
2) I have tried to point out that such question is wrong to ask and there is very simple reason for that. It will attract only people who have succeeded in doing that: they will write what they did, maybe how they did that and maybe will try to identify reasons why they succeeded (not necessary correctly).
For every successful startup there are 10 unsuccessful (unprofitable) and if stating the reality is complaining then well OK - all who downvoted me has right to live in their rosy dream illusion world where they get rich just by reading HN.
2. The OP asked a question, and you questioned why they should ask. More importantly, you merely pointed out that yes, people have, and have not been successful at it.
3. If you intended for something else, you weren't clear. Mostly because you didn't say anything. What you did say didn't amount to something that offered anything constructive, hence the down votes.

But see, you didn't say that. You didn't come close to saying that. You might think you did, but I assure you, you didn't come close. Your comment wasn't insightful or intelligent. You wanted to know why you got down voted, I told you. Don't try and now pass this off by labelling those who down voted you.
