Greg, thanks for making the change, I appreciate it.
I'm fine with having an "online presence" - if you search for my name you can find a lot of information about me, my achievements, my work, and even a couple pictures of me. I'm certainly not naive about the lack of privacy on the internet, and I am discerning about what information I make public.
Like Mo, I'm fine with people going on YLF and looking at pictures of me, using my real first name, etc. No matter how popular YLF becomes, the chances of my students or colleagues coming on YLF, finding me, and then thinking less of me (since they chose to visit YLF) is VERY slim. It's people finding my pictures by searching for other things through google (or similar engines) that makes me uneasy.
Anyway, I hope that this thread has been helpful for some people.
