Bloomberg BusinessWeek: Experts estimate that Facebook's net work has reached $41 billion. That puts it ahead of eBay and moves it into third place on the list of most valuable U.S. Web companies. Google and Amazon are number one and two, respectively.
There is certainly good cause for Facebook to have a tremendous valuation, said Forrester analyst Augie Ray. It has in fairly short order -- just a couple of years -- gone from being a very niche site to one where the majority of Americans spend a great deal of their online time.
