... what you are a "nerd" for. We're all nerds for something. That thing you cannot get enough of or know enough about. The one that would make you the perfect "Phone-a-Friend" if your cousin were asked about it on a game show.
Bonus! It's now socially acceptable. Nerd for model trains? Join the NMRA for the promised "portal to more fun in scale model railroading." Jazzercising, knitting--with the vast and varied Internet community you're sure to find others happy to be nerds for (fill in the blank) right alongside you.
So, this week declare what you're a nerd for. Tell us why and, while you're at it, share any favorite sites or resources--just in case you have a lonely fellow nerd out there. (Nerd for handmade gifts? Visit Morphologica's web site on http://www.etsy.com/ for necklace pictured here.)
