Yes,Its coming,..The secret "CSS class" or "div tags" which can be used by webmasters to secretly tell Google about Nofollow links. But in this case only the webmaster and Google will know about it.This feature could be configured through the Google Webmaster Tools.There will be an option to add a secret CSS class or a div tag which will be ignored by the Google crawler. for example: <div class="mylinks" id="sidebar"> <h2><a href="http://forums.digitalpoint.com/">Digitalpoint Forum</a></h2> </div> here either "mylinks" or "sidebar" could be used as the Google ignorant part and could be configured via the GWT. [predicted concept,what do you think]
I doubt it. There will be 100 ways to see if its a nofollow link or not within the first week. That is if it was even remotely true.
Do you have any sort of proof of this? As right now it just looks like a poor attempt at driving traffic to your blog.
Google's not going to help websites deceive other people, it's not in their interest to do it. Google would have to ask themselves if it's that important to help other websites to benefit from people who don't know their links are being nofollow'd.
