I did not post any links yet to see if they are nofollow or not but check this out. It appears that all nbc affiliates now added a comment section to all new articles on their websites. example nbc4i.com nbc4.com nbcdfw.com and i'm sure all other affiliates in the country now have the same template. Someone check it out and see if they are dofollow!
interesting...you can leave a link on the new york times site if you're lucky enough for them to approve it if related to the story!
