I really hope they understand that a large in use medium such as google itself or facebook will simply clone functionality of groupon and tweak it for it's user base ultimately killing groupon. Groupon has no 'stick' some person in rural anywhere won't have a clue what groupon is or will use it but will know what and might use google or facebook, and that's what counts - worldwide recognizability with everyday use.
