Site previously affected by Panda but untouched by Penguin is today down for lots of keywords by anything from several places to several pages.
Some of the terms affected have had no link building done on them, ever.
Interestingly, the terms least affected (or not affected at all) are those where the term is used in navigation (even if link building has been done for that phrase).
To me this looks like a boost for positive signs rather than a penalty for negative signs.....if that makes sense.
