He says Google got 100x their investment since it's 'worth' that multiple of what they paid. I don't think it's a valid argument since they paid real cash and have only a notional value in return. It's hard to see anyone forking over $100bn+ for youtube, and I doubt it's even made enough profit since they bought it to cover what they paid originally paid. None of this is to particularly criticise either the original post or its followup - it takes courage to call it as you see it and then own up to your mistakes, but it's always worth taking another pass at the figures to see if they really stack up.
