I got a fixed gear to get excited about bikes again. It worked. Just riding around was terrifying (with a brake, but i'd forget to keep pedaling and get all wonky). Then, it was "cool", now it's a challenge. There's so many skills to learn and master even if some are dumb (skidding), but others are more legit (bombing a hill, you better be spinning as fast as the wheel says you should go, or you'll start bouncing, which leads to bad control inputs, etc). Climbing is a whole nother thing in itself. Having one gear is hard enough, having to deal with that one gear being connected to the road is another. I personally would not consider riding SS versus fixed at this point... not to say I would not ride geared, but one speed riding, i'd prefer fixed.
