I often get emails from Fast Blog Finder users who ask about the “NoFollow” blogs. Is it worth to comment on a blog if it’s "Nofollow"? Does it have any sense? Won't it hurt the website rankings?, etc. are the questions many of our users are concerned about.

Well, I decided to do a case study to see if "NoFollow" links count and if it's worth our efforts to post comments on "NoFollow" blogs.
