See here. The guys who placed a $15 billion price tag on a profitless Web 2.0 company say they are very very very sure that they didn’t overpay. Money quote: For those entrepreneurs looking to sell their businesses to Microsoft, Jaffe suggested that sellers be “upfront and realistic. Don’t oversell it, because we will figure it out.” See, that was Faceberg’s genius. He didn’t oversell it. Keep that in mind, kids, when you’re launching zippr or ziggl or biggnutz or whatever. Much love to Andrew for the tip.
