If a question contains "My question is ..." the paragraph should automatically be given a different visual cue. For example, giving it a nice blue or green background.
Askers often put a lot of effort in providing pictures and information, context, but the question is so long and complex that I tend to lose track of what they actually asked, because they asked the question somewhere in 2/3 part of the text.
Sometimes I find myself in a similar situation when asking. I solve it by putting the question into the last paragraph and start the sentence with "My question is..."
Automatically highlighting the "My question is..." paragraph would force OPs to think properly about what they really ask, and help people want to answer to clearly see what the question is.
An alternative solution would be to have question formatting option in the editing area when I type the question, so that I could myself designate a paragraph as being the question.
