If you’re a student, teacher or somehow involved in the education community you’ll be pleased to hear about Edtags. This social bookmarking site is not dofollow but that’s fine with me because the content being pushed is all related and quality. They’ve obviously had a problem with spamming in the past because registration requires you to email them to get in. This makes my posting job much easier in regards to warning people not to spam, so if you have a great education site get in touch with them.
