Ms. Miami, a welcome frequent commenter here at PYY, has posted a guest post at Super Frenchie. She poses some questions about the social caste of nerds and geeks. You might want to take a look at it, it's not a long one.
Another well respected and welcome commenter here is L'Amerloque. He has a post with some interesting links (one of them is this one), as well. You may not want to miss his either, but it's a bit longer. Well worth the read though.
