My experience with MathOverflow was funny, the first time I posted a question it was almost immediatly downvoted and criticized by the moderators. Later the same day, I was surprised when my question was answered by Terence Tao, then the moderators quickly changed their opinion and people started to upvote the question.
Mathematics even worse than Software Engineering because lay practitioner can miss significance of question. If you have link to question, would appreciate. Just out of curiosity to see if I would realize why question is interesting. That in itself is a skill.
