As I read quite a few blogs, I always like it when a commenter has an avatar (picture of self) next to their comment. Even if the avatar is not a true picture, it adds interest and a personality to the commenter. Often, when someone does not have a recognised avatar, their comments on blog posts and so forth display a randomly generated image or nothing at all. On my class blog, visiting commenters are assigned a monster image. This is cute but doesn’t add a unique identity or personality to the reader.
The solution to having an avatar that will work when you comment on all blog posts is Gravatar. This image follows you from site to site when you comment on blogs and other forums. I found about Gravatar last year from the ever knowledgeable Sue Waters. She has a great step-by-step description of how to use Gravatar. Check it out here.
