Google seems to have tightened the noose further on low quality links and whatever little link equity they used to pass seems to have been killed thereby leading to noticeable rankings reset.
OMZen - Interesting difference in emphasis that I see between your take on link equity and other interpretations I'm hearing.
Some are saying that links are simply losing effectiveness after jumping two site levels (or rather, two clicks). As I'm thinking about how links should work in a Google that can take advantage of the Caffeine infrastructure, that doesn't make sense to me.
It does make sense, though, that low quality links should fizzle out that quickly.
