It's exactly like nofollow

I understand where you're coming from. I have a distaste for any of the proprietary elements introduced by search engines. And for sure, SEO-types will try to figure out a way to (ab)use any element that impacts on search engines.

But for me, this is intended to fix a webmaster's problem - whereas nofollow is to fix a search engine's problem.
