Future of Nofollow Tag
There is a good possibility that the nofollow attribute may be phased out sooner than we think. The reason for this is found by first looking at the priorities of relevant SERPs to the keword phrase being searched. If engines simply downgrade all web sites that are easy to post a link to, then there should be less need for the nofollow attribute.
Engines want their algorithms to function effectively. To do this, one of the things they implement is the nofollow attribute. This attribute is in existence to catagorize web page quality more based on true content. In simple terms, the nofollow tag reduces link spam producing higher quality SERPs.
Before the nofollow, webmasters had more of a fiduciary (position of trust) role in maintaining quality web content. The spam started occuring when webmasters, using persistence, would place their link on another site, solely for the purpose of getting a backlink to help rankings. What this did is to foster a webmaster who could care less about the content, but only cared about the new backlink. The latest increase in blogging has created the need for the nofollow attribute because most of the blog spam was made on the user's web page link mostly attatched to the Name field. Blogs showed too much irrelevant outgoing links at a time when their popularity was rapidly increasing.
What engines could be seeing now is a reduction in the usefulness of blogs. Most of these sites, from what I see, are not the best literature in the world. Also the freeness (being of no cost to user) of blogs makes them less likely to have useful resources and services.
If engines downgrade the blog and all other sites that are easy to post a link to, then there should be less need for the nofollow attribute. In other words a better change to the engine algorithms may be to give a penalty to sites that allow large amounts of free link posting. This would make unethical SEO more difficult.
