It's interesting you brought up squidoo - I was seeing a lot more squidoo this morning than in the past - sometimes up to two or three page one listings for shopping terms (to be specific, I was looking at calendars; eg, fairy calendars 2012, art calendars, etc.)
I've never gotten much out of my squidoo, and I felt google never much liked them. What really struck me, though, was the fact they were there for ecommerce terms. Kinda supports the theory that google likes to emphasize shopping in fourth quarter.
Also, some of my own listings were now appended with a small list of specific items, as an indication to searchers that I had content along with products. For example, one of my biography pages includes a filmography, and google included a three line listing of specific movies in addition to the text blurb under my link. I actually really liked that.
