There is no single factor present on every Pandalyzed domain. Rather it is quite a complex algorithm and we're sort of poking around at it. Not only that, but it is painfully clear that not every non-Pandalyzed site comes anywhere near being "quality" as a human would register it.
So this thread was asking for actionable theories. I think putting out every quality signal you can to visitors can only help - especially because user engagement metrics [webmasterworld.com] may very well be in play. After all, one of the Google questions was "would you be comfortable giving this website your credit card."
