This is fascinating, but there should be a disclaimer that reads "98% of webmasters and SEO professionals should worry about something else instead of this."

@SM - actually, I liked Michael's comment on the post that most SEOs tend to understand the value of editorial links in the content. This intuitive behaviour seems to underline that some form of DOM structured (or other) approach may well be in play for link valuations. So while speculative, there is an underlying sensibility to grasping the concepts.... and really, there is no harm in SEOs understanding IR concepts at the end of the day. It helps increase that intuitive nature IMHO...

@Steven - thanks 4 the Sphinn mate... must catch up on Skype one of these days!!
