I have never clipped in, I ride fixed, geared, everything. I'm still waiting for a good reason why I should clip in. I saw a mate of mine go flying ass over off road while still clipped in and it wasn't pretty. I ride an easy gear fixed and don't skid much but I don't see what the fuss is 'you must ride clipped while riding fixed...'. I commute to work in the shoes I wear into the office so platforms help there too.
