A great way to add comment avatars: an image (or icon) which is unique to the person who is making the comment. When using comment avatars in your blog, you will easily be able to recognize comment authors, especially those who regularly visit your blog. Also I feel this adds a greater sense of interaction between blog authors and their readers.
By default, Blogger only shows comment avatars on comment pages (either pop-up or full screen, depending on your comment settings). However, no comment avatars appear in the most visually important place: in your item pages where comments are displayed beneath your posts. Additionally, only the comment avatars of registered Blogger users may appear on these pages, so if your readers blog on a different blogging platform, their avatar cannot appear at all.
