How often do you do it? Personally, I go through quite a lot of profiles on GAG, or at least hover over everyones username. Don't worry, I'm don't really care all that much about what's there, I'm just curious, that's all :)
I do it a lot. I like reading 'about me'. Some people are very unique, creative, rollicking and enigmatic when it comes to represent something. Coverpics also seek my attention too. It says a lot about the person. I check the avatar of people too. It helps me in learning about how to capture a good photograph :)
Being an UberMod, it is also my duty to stroll here and there. If someone is harasser or troll I scrutinise their recent activity too.
I check the activity of some ingenious users too. Love reading their posts :)
