Facebook discovery

I have recently discovered that on Face book there is a total of 495 people who are named Noden and have Face book pages. They are scattered all over the world, but predominantly in the US and the UK.

Assuming that each of them has at least 4 living family members, this means the represented population is approximately 2000, Assuming that the percentage of the overall population that has a Face book page is similar in both the US and the UK, which is given as 10% of the overall population, there may be as many as 20,000 Noden's out there. This is a staggering number and makes the whole character of my genealogical inquiries very different than expected.
