As a stack overflow old-timer, I can tell you that questions that get a lot of hits from outside, (e.g. popular searches, blog post links) tend to get more visitors that are not familiar with how the site works. Many of them assume it's like a discussion board and post "answers" thanking another poster or asking a different question. I've seen this many times. It's not really offensive to claim that people new to the site are likely to be less familiar with how its intended to work.
