I started putting it on recently because I've heard from a lot of photographers on the web that you need to protect your shots and this is one way of accomplishing that. Picasa, for me, made it easy because it will stamp it as it goes out the door so I thought I'd try it out.

I do, however, find it kind of distracting, even on my own and I think mine is pretty small. I'll probably flip the other way and not bother with one as, frankly, I'm not sure that it makes a difference with respect to having people steal your shots.

I guess what I'm saying is that I'm confused too!
