Wow. Thanks for the responses.

It's more of a utility question about the clipless that also stresses the utility of the flipflop pedals.

There are certain days when I need to use the bike to ride to a train to a meeting and I can't go with the clipless. Also, I often stop and shop from the bicycle, so I can't really walk around the shop in another pair of shoes.

It seems like the only way it really works is if someone rides from one pair of shoes to another

However, a flipflop platform would allow people to use both should they want (clipless and non).

I guess my bike is more of a car substitute and more than 75% of the time I stop somewhere while commuting each day!
