Re: Zuck will spend most of that money, however, on a gigantic tax bill.

>50%?? Huh ??

I can't claim to be an expert in US tax law (who can, really?), but as far as I know, capital gains tax in the US is 15%, and I'm sure his well-paid army of accountants and lawyers will see to it that he's not paying more than that. State and local taxes are mostly sales taxes.
