Ad Revenue Heading Up at Yahoo

Om Malik has a report that says advertising revenue is over at Yahoo Search spiked last quarter at a rate nearly four times the web average of 1.7%.  My question is why? Ever since Jerry Yang took back the helm, word in the Valley is that Yahoo people are hopeful.

Hope is one thing, but there is no evidence  that I've heard of anything changing over there. Certainly there s no hint that Yahoo Search is gaining on Google. No one seems to have a clearer articulation of a Yahoo vision.  The beta remake of My Yahoo is nothing to blog home about.

So why is ad revenue spiking? I don't know.  It's a mystery.
