I think this topic is interesting because I always wonder what the benefits of riding SS are over fixed.

I started riding because I thought fixies were cool. At first it was all about the novelty of "learning how to ride a bike again." If you don't of think that experience as a fun adventure, you may not understand why a lot of us liked it so much initially. After riding for a while I started to notice some of the less vague benefits; most of which were mentioned before.
- Very low regular maintenance. Just lube the chain and put air in the tires.
- Excellent low speed control. Helpful if you are biking around a busy campus.
- Track stands get easier. Really nice skill to have in stop and go traffic if you're clipless or slow to clip in.
- Lighter weight, all else being equal, than a road bike. Makes acceleration and climbing easier. (Shed ~450g fixed over SS due to extra brake equipment)
- Controlling speed by resisting begins to feel much more fluid and natural than using brakes
- I feel like I pace myself better on FG because I'm constantly pedaling. You really get into a rhythm better. I'm sure there's some exercise benefits to not coasting too.

As others have said, it takes a week or two to feel "zen" with the bike. If you give it a shot and you still don't see why we like it, it may not be for you.
