I've had some questions about my avatar, and no, I did not create it myself. It comes from an online avatar/character generator created by the very talented Rasterboy.
Check out his Unique character generator here.
Every comment I leave on my blog and those of other's display my avatar because I have a Gravatar account.
From their site:
A gravatar, or globally recognized avatar, is quite simply an image that follows you from site to site appearing beside your name when you do things.
