I saw this over at New Order (its a few days old, so I hope I'm not repeating what someone else posted)
It's a pretty good survey with lots of questions that really test your computer nerdiness, like
0039 Ever define your own numerical type to get better precision?
0145 Ever used == for = in math class?
0146 ... put a ; instead of a . at the end of your sentences?
0147 ... Did your teachers give you a funny look?
Check it out, it's a good/funny read.
