I'm a little surprised to see that they provide more answers, but that they aren't of better quality. I would have expected experience to show more.

Of course, we only know they are older, not that they have more years of experience.

I think its one of those things where the real issue is if you have an answer at all. Of those ppl that have answers the quality of answers, I'd expect to be similar (across a population).
