Looking back, I see a big dip in Google traffic on 11/21-22 on my Penguinized/Pandalyzed site, but then the traffic shoots up on 11/23 to a modest increase which has been holding ever since. But I don't see any shifts around the 27th. My site is informational
Exact pattern to our "April 24th" affected site as well. We're also in the informational niche. I mention all this strictly as an observation.
