I think it was the type of keyword. Panda 1 sites ranked for the trophy one word and two word keywords. Panda 2.1 sites ranked for three word keywords and long-tails.
Panda 2.1 sites were less important in G's eyes as they were sending less traffic to them.
I thought about that but my one pandalized site does not fall in that category, I normally rank /ed for 3+ words and that's perfectly normal for my niche /domain aname. I am thinking that maybe G targeted top XX% of the 'worst' sites and then tried to expand in other Pandas, going back and forth by adding /removing /changing filters.
But you theory could explain why many cheesy 200 or so word single focus 'sites' still rank. They're under the radar where bigger sites that sent spammy signals like too many tags etc were caught. Probably just a mater of time before G removes the smirk from their faces :)
