If you are a blogger and want to give a face to the comment writers of your post, the Gravatars i.e.globally recognised avatars are here. It will give a feeling of identity to comment writers who are not having an avatar in wordpress. You will start feeling as if there is a community of visitors frequenting your blog.
There are three types of system generated avatars available on wordpress. Now, I will always prefer generated one in place of the big blue G appearing for all visitors. There also a conflict of choice is present. And finally, I have settled on wavatar. It will give a unique face to each of the blog visitor. But only thing is that the face will be a bit funny, which is badly needed for my serious kind of blog. Don’t mind it friends, it is web generated. Keep posting your comments.
