I love my fixed gear. I do run a front brake, mainly for 2 reasons: I would wear out the rear tire real quick skidding to a stop all of the time and some of the hills around my way are so long, steep, and twisty it would probably be a death wish to not run the front brake.
Thanks for that post Jon. Working in downtown San Francisco I get to see the bike messanger going down the steep streets out here on their track bikes. It's amazing seeing them skid their way down a steep incline with no brakes.
