eBay Calls on Google

``This is a bold move by Google. They are striking hard at a nearly $12 billion/year Microsoft revenue stream. And they are clearly trying to get this out the door fast, in anticipation of Microsoft Office 2007, which will include collaboration features for businesses,'' writes Michael Arrington, on the blog TechCruch.

Investors who are growing increasingly worried about the economy will want to see payoffs a lot quicker if they are going to bid up Google's shares, which have slumped 9% this year.

Shares of Google rose $2.93 to $376.19, while eBay rose 70 cents to $26.
