I think many are being too quick to dismiss just how much you can learn from an avatar. It can tell you a person's political affiliations, their sense of humour, what they do for a living, and much more. My avatar is of H.E.L.P.eR. from the Venture Bros., and that can tell you about my sense of humour and you can get a pretty good idea of other things I may like/dislike. My previous avatar demonstrated a taste for irony and nostalgia, and before that Canadian literature and graphic novels.
Sometimes I consider changing my avatar to be about something I have no idea about, like a character from a television show I've never heard of.
that assumes one knows who H.E.L.P.eR. is
and i recognized you as a familiar poster only after i noticed the location, and then looked at the name. i liked your previous 'tar (this one is too dark), but why should have it been about irony and nostalgia?
