Like masks of any kind, avatars hide and reveal at the same time. Behind it, people can conceal some personal things about themselves, but the av also selectively amplifies other aspects of their personalities. It may reveal something about the member that otherwise is not immediately obvious - maybe not even obvious if you met that person in real life. Maybe not even obvious to the owners themselves. What users express in their props is not always a conscious choice. Sometimes it’s unconscious. People may simply say that they are wearing a particular av because “I like it.” When asked, they’re not sure what it says about them. But other people may know.
