It may not sound like a serious question but it is one with a serious answer and one that could show us all where the internet (and commerce) with it is going.
As no matter what you say large companies don’t get rid of billions of pounds or dollars without good reason (ok HP could be an exception, and for the record they bought into an area of growth, just perhaps the wrong company or the right company at the wrong time.)
So it “could be” telling where they put their money. Yahoo under MM is going for location and mobile and a little bit of social too. And doing so relatively quickly and aggressively.
Not surprising as they got a LOT of catching up to do.
