Some of the links that my plug-in shows is the feed burner links to the post. Some has a direct link or permalink to their post.
Upon investigation which happen also to this site.. Some of my commenters used the feedburner plugin that converts all feed request to be redirected to a feed burner.
So to all of you who are commenting to the Comment Luv Plugin activated site with an aim to communicate and at the same time advertise your feed links, I would suggest to deactivate the feedburner plugin and change all links at your homepage to have a feedburner feed request links.
Just a suggestion. It is better to have a permalink that is directing at your site rather than the feedburner links. I have deactivated my FeedBurner FeedSmith plugin because of the above mention criteria. In an SEO point of view, using your permalink will give juice to your blog and using feedburner links will give link juice to feedburner so the decision is yours.
Now you can start commenting in different blog who support the comment luv plug in here
