Semi-tangential, I took my fixie to Harris Cyclery for a tuneup before it closed. Boy, was I floored when the guy working at the counter told me that fixies weren't cool anymore. Sheldon was a big part of my journey to riding fixed gear. I learned everything I know about bikes from his site and he even answered questions personally by email.
I'm pretty sure when the guy said fixies weren't cool, I heard Sheldon spin in his grave a little.
