Although majority of ZooChatters have profile pictures, it has always puzzled me as to why some members don't have one. I understand why many of the newer members have blank profiles, but certain long-time members such as @Terry Thomas and @Pertinax still don't seem to have one, despite being on the site for years. Out of curiosity, why do some ZooChatters choose to have their have their accounts this way? Do they think it just look better, don't have any idea of what picture to use, etc?
