I don't know how sites like squidoo continue to survive post panda.
However, there is a write up on squidoo about the effects of Panda on both squidoo and hubpages.
Basically, according to quantcast data, prior to panda, the traffic for hubpages had been significantly higher than that for squidoo.
After Panda1, hubpages started to get about the same - or slightly less - traffic than squidoo was getting.
Squidoo traffic seems to be holding steady but that article mentioned a slight rise since April 11th. There was no data on that page regarding whether this traffic has been sustained.
