Changing avatars, what do you think?

I’ve noticed that some people like to change their avatars. Something I became aware of today is that an avatar can influence the way I see/think of a person.

Have you noticed that avatars, and the way you perceive them, influence the way you perceive the person they represent? The subject just seemed to provide food for thought…
