The guy may have a point
While there's a strong possibility that Google would have killed it anyway, I think Yahoo's management certainly did it no favours. I used to advertise on Kelkoo a few years back (for a large entertainment products retailer) and it was pretty successful, and the management seemed to have a plan. Yahoo! took over and that all went titsup fairly quickly. And its certainly not the only Yahoo! acquisition to quietly die in their tender care; anyone remember GamesDomain? Or All Seeing Eye?
