Blogger by default, and other blogging software such as WordPress, automatically adds the “nofollow” microformat extension to all links from user generated content. User generated content is defined as comments or external sources such as linkbacks and trackbacks.
I support the people of the blogging community who have chosen to remove NoFollow for blog comments and linkbacks/trackbacks and I highly recommend others to do so.
Removing the “nofollow” attribute will help people who are giving you comments to increase their website/blog PR (Page Rank). I currently set the lower limit to 1 for my blog, so feel free to comment, 1 comment/user will help you raise your PR 🙂
