Some consolation at last. Thanks, Mark.

There are indeed quite a few questions closed as off-topic. I did not base my point simply on my own question. But yes, your answer and the answer by John S Gruber clarify everything. Ask Ubuntu is not about providing solutions to everone who asks a question, it is about juxtaposing the questions and their possible answers in a manner that later users with similar problems can browse them and find a solution to their own problem. I am satisfied with this answer.

Thanks for your answer. Yes, I now understand the whole situation, and will surely avoid making the demands like the one you have quoted. That is exactly why I have asked this question - to get things clarified. Because for someone who installs Ubuntu, finds a problem, searches for its solution on the Web, and runs into Ask Ubuntu, this is not very obvious. His natural instinct would be to somehow get rid of his problem through Ask Ubuntu without giving a thought to conditions of this forum. I only wanted to present the end-user side of the story.

Let me try and give a straight-forward answer. My point is that if I buy a system which run Windows without any bug and runs Ubuntu with a bug and then if I ask a question in Ask Ubuntu, and if the question is closed as off-topic, I have 2 options. Keep waiting for the bug to get resolved until eternity or install Windows on my system? So as a Ubuntu enthusiast who was all eager to give up Windows for the sake of Ubuntu, Ask Ubuntu didn't solve my problem. I asked that matter-of-factly and not as a threat. Anyway, my question has been answered in the best possible manner by John S Gruber.

This is the most prefessional reply to my question. Thank you very much. I now feel part of the Ask Ubuntu community once again.

@EliahKagan, thanks for your reply, but earning minus reps does feel like a punishment. Please note that I did earn a -2 on my bug question which was only undone after I complained about it.

4. He would revert to Windows because for the system that he just bought from the market, Windows would present far less bugs than Ubuntu.

3. How is a new user to know if the problem he or she faces is a bug or a just a "problem"? If it is not a bug and the user is smart enough, surely he or she can find the solution even without Ask Ubuntu. And if it's a bug, he would receive a rebuke from Ask Ubuntu as if he has just committed a grave offence.

2. Stumble upon means stumbling upon the solutions not problems. Obviously stumbling upon solutions to the problems the user had beforehand.

1. Regarding bunch of experts talking in the jargon he or she can't understand, I am not talking about any specific experts or questions, I am talking about the predicament of a user who has migrated from Windows to Ubuntu because of Ubuntu being Open Source.
