I've read through the sample questions in the area51 proposal and I don't see any examples of questions that encourage users to share experience so I'm not sure if they are appropriate or not.
Here is an example:
Question: What is your best recovery after a goof-up?
Description: We all make mistakes, even Tiger Woods hits the ball in the trees sometimes. One of the things that makes Tiger a great golfer is his uncanny ability to get himself out of trouble. What mistakes have you made doing home improvement and what creative ways have you used to "get out of the trees"?
Would this be an appropriate question? Assuming it is, would it be worth posting something like this to encourage share experiences or it really not the type of question likely to generate interest?
It was this question about tools, that gave me the idea.
