That's an interesting graphic, and somewhat hypnotic. I was born in 1968 and there were a lot of Michaels in my elementary school class, and I was one of four Davids. My son Ethan was born in 2002, and he is once of five Ethans in his elementary school class. We chose the name Ethan because in 2001 it was number 17 or so in the most popular name list, and then shot to number 2 in 2002. Strange how that works out.
