I don't know how everyone else is doing, but since the anthology release I've seen two small sales spikes, and today one huge wave of KU pages. I've also seen a change in my activity in non-US markets, with more than usual going on in the UK, Germany, and India. Though my sales aren't huge, and I do see a lot of fluctuation anyway, I have to think some of this is due to the cross-promotional impact of the anthology.
