I don't know if I could pinpoint exactly when this started for me, but I realized the other day that I never read the questions when I'm trying to debug something and SO pops up as part of my Google results. I just read the title, then scroll down to the answers to see if any of the proposed code will work for me. Maybe 1 in 50 I'll flip back up to the question to see if a specific variable or setup is mentioned and therefore used in the answer.
I have been wondering with the discussion around SO culture and community if maybe this is important. For all the discussion about "good" questions and wanting to archive generally applicable programming advice, would it change the assumptions about the value of either if it turns out that people aren't reading the questions anyway?
