People love to take photos of their feet. I'm not sure why. Maybe it's because we're so used to staring at our feet while waiting for the elevator to arrive or doing sit-ups that it's nice to look down and see them doing something relaxing. It's like, "Hey guys! You're on vacation! Pose for a photograph." The only more popular photos that I see are when two people smash their faces together and get a close-up shot, usually someplace on vacation, but it's not like you can ever tell. And the other popular photo is sunsets. Why are there so many sunset photos? I suppose it's because the light is always so good that time of day.
