My_Media, this is am interesting idea you bring up. It does look like some factor has floated small junk sites up in the rankings. Whether that is specifically Panda's action, or simply an effect of the machine learning we often see after any significant ranking, is hard to say.
We do know that this second international round for Panda included something they called "long-tail" evaluation - for page's that could not be done on the first round because of some iind of capacity limitation.
