¿Qué es un avatar?
I see the word Avatar on this web site. What is the meaning of the word Avatar?
I should have added in my answer, that you might pick a little bear as an avatar, by the way ... a second little bear, because you are littlebear2!
I clipped this from an ad that was on the same page as this thread when I was reading it. Something like this could be used as an avatar.
Oops!. Look away! I just saw the copyright symbol.
Your question is answered very well by an article in Wikipedia: http://en.wikipedia.org/wiki/Avatar_(computing)
"An avatar is a computer user's representation of himself/herself or alter ego, whether in the form of a three-dimensional model used in computer games,
 a two-dimensional icon (picture) used on Internet forums and other communities
, or a text construct found on early systems such as MUDs. It is an object representing the embodiment of the user. The term "avatar" can also refer to the personality connected with the screen name, or handle, of an Internet user."
You see it used here in that first sense. And you can upload your own avatar as part of your profile.
I was thinking about using an avatar myself, instead of my picture, but chickened out feeling unworthy of the avatar (icon, two dimensional picture) that I would have wanted to choose but not wanting any other, either.
I think you will agree that avatars are a lot of fun! Lots of people use them here at/on SpanishDict.com.
