Microsoft & Yahoo - Together at last?

How can your friendly neighborhood business correspondent pass up a story like this? Microsoft has just made a $44.6 billion bid (yes that's a "b") to buy Yahoo. The move comes following search giant Google reporting pretty sad earnings for the final quarter of last year.

The bid is an aggressive move by Microsoft to gain dominance in an area where they're lagging: online advertising. Google's expertise is search, but they make their money in internet advertising. And they're really good at it. But with its tepid recent earnings and Microsoft's latest move, could the Google juggernaut be in danger of hitting a wall, or at least a bit of molasses? What do you think?
