This blog was once known by my true name. Problem was, periodically business contacts or interview subjects would google my name, and the first thing they came across were my blog postings. This occasionally led to some odd interactions. I figured I needed a bit more distance from the blog, so I renamed it. My true name is embedded in the url -- but of course from google's perspective that doesn't matter.
I also removed links pointing to my eponymous domain.
It worked. Now when I google on my name the blogs are all but invisible.
An interesting lesson in the effervescence of digital identity! A certain kind of anonymity is not hard to achieve.
