Not if you ride SPD. They make freestyle MTB shoes now that look like skateboarding shoes and position the cleat fully recessed inside the sole. And of course, you can get SPD sandals (gag). Not stiff enough to ride 40 miles with the local "A" group, but more than enough to buzz around town.

The biggest benefits of clipless on a commuter are: no foot slip during wet conditions, while climbing, or while sprinting to make it through an intersection. Platforms work perfectly for commuting 95% of the time. That last 5% where you slip off a pedal swerving to avoid a clueless pedestrian or vehicle, whack your man parts on the TT, and crash. Biggest problem: you will probably tip over after forgetting to unclip at least once. It won't hurt too bad, but it will almost certainly occur on camera or in the presence of close friends. Not that I speak from experience, of course.
