Just did my first "fixed" ride the other day. I've been riding singlespeed for awhile, and of course when I was young that was all I had. My first ride on my 2008 Madison was awesome. I learned a lot, but I know that I need a lot more practice before going into heavy traffic, etc. I rode on a controlled, paved path and all was good. I did have to deal with some ice and snow, but just soldiered on and kept it pointing straight ahead and I didn't lose it.
I would be interested in any pointers on technique. I have two brakes, so that helps, but I would be interested in any tips on slowing down without brakes, (i.e. backpedalling), or anything else that comes to mind. I'm looking forward to better weather so that I can explore this fixed thing some more.
