It's interesting that there are two noted under project "page quality" one of them being the penguin data refresh, and the other being the detection of hacked sites.
I'm still seeing quite a few hacked sites in the results for searches I track. They emerged during the first Penguin update, and many haven't gone away.
Project "Page Quality" still has a way to go, but I'm actually pleased to know they are working on site hacking. I just hope they don't think they are done.
