Same here and today looks the same. But cant really complain much becouse i been enjoying very good payouts! But yes yesterday and so far today its in the dumps and forget about tomorrow. I expect it to be dead. Hoidays usually suck.
Average yesterday for me...2 sites are a little slow today in terms of traffic, but nothing abnormal for me.
did you look to see if the ads changed or one of the advertisers may have dropped as of the past 3 weeks only change i see is when an advertiser drops... which you see this happen in google but its not as drastic as the next advertiser is only a few cents under where on some on Yahoo is a dollar or two....
I have experienced a drop this week, but this does happen from time to time as advertising rates fluctuate. Yes it is frustrating, but you have to deal with the frustrating days as well as the good ones.
