Story in this morning's Wall Street has some interesting bits concerning the Sistrix study mentioned earlier in this thread, and other threads. Their reporters apparently talked to some major content farmers, who confirmed the Sistrix data:
Several owners of sites listed in the [Sistrix] study agreed that it assessed the impact of Google's moves on their search rankings accurately.
Johannes Beus, Sistrix's founder, said in an email... "Google aimed at low-quality pages and it looks like it did succeed," he wrote.
