Paynt - great observation. If it is indeed a global change what a great way for Google to put some of the relevance power back to normal text rather than links all the time. It seems a very smart way of getting rid of much scam and spam. Who wants to go to a page that just leads you to another page anyway? I want to go directly to a page that has content about the subject, not one that directs me to another page that has content about the subject.
All power to non-linked text! I had a feeling that Google was maybe overdoing the emphasis on link text anyway. Taken to it's extreme, this could mean more hits to interior pages of sites (that's good for the searcher! - they can move from the specific to the general rather than the other way around) and lead better to actual original sources rather than second parties who quote them.
