Sites that have been around for 15+ years do not suddenly go bad overnight which is what has happened for many of the Panduin cases I have seen. Just why is it that Bing can tell the quality and originals whereas Google cannot? Certainly in my widget sector Bing can.

Seems to me Bing takes a bit longer to index page than Google does, but once it gets around to them, it has a pretty good, stable idea of where they belong in the rankings. I haven't encountered dramatic shifts in Bing rankings.
