Yeh Linkedin just bought www.Lynda.com overnight to integrate into the Linkedin platform for $1.5bn and it has been operating since 1995 doing US$150m in annual revnue from it's learning subscription service.  

So Linkedin paid x10 Lynda's annual revenue and it integrate the service into Linkedin - so tell me the logic behind www.1-page.com $250m valuation again with $225,000 in subscription revenue?

How about giving some solid numbers to the market as in how many customers/user are paying for the 1-page service how many are free.
