I agree with the hidden potential behind nofollow links but it still needs to be a link with high virality it seems to achieve any of the benefits listed in the article. What I’d be interested to find out is if there are any hidden powers of nofollow links for search engines itself.
No I don’t think that’s the future of SEO as in there will only be nofollow links in the future. For internal links at least, you’re not likely going to use nofollow tags for them right? Also, I think that there are still a great deal of people who are unfamiliar with nofollow tags/links.
I definitely agree on this – dofollow is more valuable, but links whether they’re nofollow and dofollow act as referral, and these links could be a source of traffic. We need traffic more than page rank juice.
