I understand why people do social networking, and it’s easy to see how making the “front page” of a well trafficked social network would help a website. But the philosophy of “tagging” or submitting all of your own work to social websites is one I don’t agree with. First of all, it takes real time to do so. Secondly, the pages that link to you are of very low quality. Add to that the presence of the mis-used “nofollow” tag, and you get some very weak links.
