$100 million is rather less than 1% of Zuckerberg's wealth. Little old ladies donate higher percentages than this. Donations, particularly ones which smell an awful lot like quid pro quo, don't count for much in my book unless they truly hurt.

And when he donates all but $5 million, ideally anonymously, then I'll be impressed.
