Backlink Evaluation Change?

Interesting snippet about four snippets from the bottom of Google’s Search Blog for Feb 27th regarding how they are switching off a method of link evaluation they have used for years! It appears this is particularly in relation to how they figure out the topic of the linked page.

Their snippet reads:  “We often use characteristics of links to help us figure out the topic of a linked page. We have changed the way in which we evaluate links; in particular, we are turning off a method of link analysis that we used for several years.”

Any ideas as to what this might be? Anchor text? If thats the case there could be a bit of pain ahead for some backlink builders and SEO’s particularly those who rely on backlinks a little too much. I’ll be watching the famous search example of “click here” to see if ADobe’s pages fall in the rankings over the next few days.
