It would not affect me personally since i don't rely on
PR for SEO, mainly i check SERPs (i don't even check backlilnks, as long as i rank on the SERPs). But it will affect others, not in seo, but in
business with the text link sales, but i am sure those guys are smart and won't let this business go down, they will just find a new way to give a value to their site for selling text links (they = the text link sellers).
