There in my referrer tags was planetilug.draiocht.net (though I can’t figure out why), where I found a link to the nerd test. Two posters who’d taken it scored 80 and 96. Just as Gareth Easton said “I thought I’d give it a go… I answered truthfully (I’m ashamed to admit) ;-)”
My score? 90th percentile:
Supreme Nerd. Apply for a professorship at MIT now!!!
Of course, I’m a sucker for even the most ridiculous of personality tests.
