Google, clearly, is a great business, but that does not make it a great investment. Even if you can live with the two-tier structure where new investors will get shares with inferior voting rights, and even if you think the employees will remain as motivated when they become rich beyond their wildest dreams, and even if you believe the company will survive all the tensions that follow, internally and externally, from the decision to go public, you should still be in no rush to invest.
