That's my experience exactly. I've never even thought of joining (since I was about 12). I'd far rather have a conversation with a construction worker or truck driver over some beers than be inundated by inanities from a bunch of jerks. (Ideally, of course, I'd prefer to be with PFers and some beers

) I've been in discussions of totally elementary subjects such as nuclear power generation with people who hadn't a clue what they were talking about except that they
had to be right because they were geniuses in the top 2% of the population. I never had the heart to tell them that I'm in the top 1%, but it was tempting. The people who utilize their intelligence (any form thereof) in a useful manner are far more valuable than puff-balls who can't get over themselves.
