What are the most valuable Websites on the internet and how much are they worth?

I remember hearing that myspace sold for hundreds of millions of dollars awhile ago. What are some other valuable websites and what do you think they are worth? Example is facebook.com a college photo site. Any ideas?

I heard business.com sold for 1mil


myspace sold for 568 million facebook wants 2billion.








I think myspace is currently worth the most because it targets youth, which are the socioeconomic top spenders.





alexa.com has the top visited websites extrapolated by who uses their toolbar.
Reply:The Giants of the web: Google and Yahoo.





I don't think they will ever be on sale, or if a price is high enough to buy them...





They worth billions
