Anecdote: I found seeing the various usernames on the platform quite nice when I used OKCupid a few years ago. When my now-husband and I met on the site, some of our first discussions were about why we chose the usernames we did.
You mean culturally homogeneous people. I guarantee those names are arranged in a Pareto distribution, in which the vast majority belong to tiny numbers of people, while everyone else has names that are common within their culture, be they Michael or Mohammed.
But I presume you're one of those delightful "white people are boring/unoriginal/have no culture" folks, so carry on.
Basically an easier to read name.
