I mentioned a few days ago that I had chatted to a makeup artist who stopped me at IMATS to tell me that she read my blog, and joked that she was stalking me on my blog.
Out of curiosity, I wondered if I could find her using Google search. The first search turned up a web site that I suspected was hers, so the second search was an image search for the name of the owner of that site, and the very first photo result was her.
It took around 2 minutes to go from "I wonder if I can find her" to "Yes, that's her", while looking at her Facebook profile photo! Of course, I sent her a friend request. :-)
While it's good that you can easily find something or someone that you're looking for, the downside is that someone else can do the same to you. For example, I postulated that if I can find someone that easily, surely with the right search terms (probably a very small number of words), it would be trivial to work backwards from my female online persona to my real world life.
The answer is yes, it is. Then again, with how out I am on facebook, and in real life (particularly with my nails), I don't greatly care if people join the dots.
