I just read this article from the NY Times about people who look for other people with the same name on the Internet. The name for the people you find who have the same name as you are called “Googlegangers” (the “a” is supposed to have an umlaut over it, but I can’t figure out how to do that and don’t want to spend the time).
Much of the article is about the attraction that people have to people like them: names, birth dates, ethnic group. It also mentions that there can be a kind of rivalry among people with the same name; it mentions a Jon Lee who wants to be the first Jon Lee to turn up in a Google search trying to stay “ahead” of other people with his name.
I’ve never met anyone with the same name as I have, and if I ever search for my name on Google (which, I’ll admit, I’ve done), I’m the only one. It probably comes from having a Dutch last name that isn’t incredibly popular, and a first name with Hebrew origins that (according to this web site) ranked a lowly 388th among most popular boy’s name in the United States in 2006 (What was the most popular one? Jacob).
I have the opposite of affinity with people with the same name as me, I think. I’ve got a lot invested in being unique, and if I were to suddenly find another “Elliot Ritzema” out there, I think I’d be disappointed.
