One of my favorite WordPress plugins is Comment Luv, and I have finally been able to add it to my SEO Diva blog after a theme upgrade.

Comment Luv is a nice way to thank a visitor for leaving a comment on your blog by automatically listing the most recent blog post for their blog, with a link to the article.

Head on over to SEO Diva and try it it out - leave a comment and see your most recent blog post appear below it.

This won't won't work for blogs on AR itself, but should work fine on the AR outside blogs as well as any other type of blog. It's a way to get a free link to your blog, plus a little ad for your blog post.
