When someone comments on your blog and writes a comment with his/her URL, is leaving more information than you think. This plugin displays web pages and profiles of those users in the dashboard, so you can add them as friends if you are in the same social network.
This is possible thanks to the Google Social Graph API. The profiles are showed because the commenter claims them as its owner on his web linking them with <code>rel="me"</code>. The ones which are with italic font are not reliable and they could not be of the user.
Comments, questions and bug reports are welcome: <a href="http://www.berriart.com/meet-your-commenters/" title="Meet Your Commenters" rel="nofollow ugc">http://www.berriart.com/meet-your-commenters/</a>
