I don't like Mark Zuckerberg much or find him remotely impressive, but it's not even the comparison so much as the diminutive connotations of "the next". If you're truly great, you're not "the next" anything. FDR was not "the next Lincoln", and Obama (whom I expect to be our generation's great president) is not the "next FDR" or "next Kennedy". I believe he has the potential for FDR stature and Kennedy charm, but he is and is going to grow into someone entirely new and singular.
