Well, I guess it's an anonymity thing. It seems that so much of your personal information is in a public domain these days, it can feel more comfortable hiding personal details, including photos. That being said, I know what you mean, it is nice to see pictures of people, and some of my friends on chess.com have photo albums. I guess there isn’t really a risk, it might be something I consider.
P.S: I notice you’re a Londoner. Do you play at a chess club? I’m trying to find a nice one around where I live, which there doesn’t seem to be.
Why don't more people put up a photo of themselves? It makes it so much easier to recognise people who you have played. I play with so many people on this site but it is the ones that display a photo of themselves who I remember and have the best games with.
I estimated that only 6% of you have photos.
Please consider this and put your photos up.
