I'm in the middle of link building for my site and I found an .edu blog which autoapprove comments. I would like to share it so you can get an edu backlink. But please do not post spam comments! It's nofollow but who cares, an edu backlink is still good no matter if it is nofollow.
no-follow and do-follow backlinks should be equal so it will look natural.
anyway, going back to .edu links. whether it is a no-follow or a do-follow link, .edu backlink has its authority already and it carries a high quality link pointing to your site.
