I have come across one guy who has a very popular blog. Totally original content, no greyhat SEO, and very useful site too. He has been hit badly. He will survive as he has always had a large dedicated following.
But this is one example which convinces me that Google has botched up this update. I can see some regular low quality sites vanishing, only to be replaced with even lower-quality ones!
Considering that even an ehow is actually better than 99 % of what is out there, whether it would even be possible to algorithmically weed out low quality is doubtful. I might be wrong...
