As of today the links in the comments section do not have the nofollow attribute anymore. So those that will comment on any post will get a link back to their site and that will add to their page rank. I'm using Oliver Bockelmann’s Nofollow Case by Case plugin that will remove the rel="external nofollow" attribute from links in comments. Thanks to Martin Reed of communityspark.com for his idea about making a blog link love compatible

The side bar also shows a top of those that commented the most with links to their sites ( also with no nofollow ) . I'm using the Show Top commentators plugin for this, thanks to John Chow for his ideas about how to increase blog comments

Some think that this will just increase spam ? what do you think ? do you show link love on your blog ?
