Funny, I had a major dropoff 2/27 and 2/28 as well. My CTR and CPM were about one fourth the normal... traffic was nice. I'm tending to believe in normal fluctuations, but it's quite amazing that one day can be 400% greater than the next. I'm only at about 750 page views per day, so maybe my sample is just way too small.
