Co-workers finding you in virtual worlds

I logged into the virtual world of second life today to find a strange message from Aeron Undercroft. They addressed me by my real life name and asked if I was there. I replied asking who they were and how they knew me. Unfortunately, they were not online. I don’t mind that people know me in real life. It’s just that I would like to know who it is that knows me, or why they know me. Later in the night I find a newbie walking around my shop looking at different things. I begin to make a small conversation and find that they heard about second life through my blog. Impressive … only it turns out that they know about my blog through me! This was the same person that I work with.
