even though the stuff being returned by the link: operator is a lot of nonsense, i still think that backlinks being downgraded are a good explanation for some sites taking a dip after Panda. if google decides that a site is low quality, i dont understand why they would continue to treat their links as high quality.
if an otherwise decent site finds that it has been demoted after Panda, and cant find any real reason why, then surely it is a possibilty that the quality of their backlinks have been downgraded.
that might also partly explain why branded sites are getting a boost, because their backlink profiles are usually so much larger.
a lot of spam sites have large link profiles too.
