I think Milo could work. It is a little bit trendy, but I don't know a lot of people named Milo. Blending into the ethosphere is definitely a common practice. Joe Johnson and John Smith and the such. My only issue is that Joe is so overplayed. I know 50 Joe's in my network.

I could be wrong, but my thinking was that it could be harder for YOUR instance of John Smith to rank to the top of Google if you have to compete against 3 million other John Smiths. Versus, telling people to "Google me" and you are confident with 99.9% certainty that your information will rank at the top of Google, considering you are the only person in the world with that name. My thinking was that this was better for business.
