Ok... the most obvious change that I can see is that since the weekend there are a lot more sites that at least look halfway legitimate suffering from -950 that used to rank. The number of sites sent to the end of results has at least doubled - if not tripled in the past week.

Whatever the changes were over the past week, one way google dealt with them was to send them to the end of results. There's no doubt about it in my mind. Search the end of results in any competitive niche. You will find a fair number or recent additions.
