Hrm. Obviously this is a good thing, but...
Wikipedia tells me that Brin's net worth is $16.7B. Very roughly, my "net worth" (in the sense of assets required to duplicate my income) is $2M. So that's the equivalent of my dropping $59 on them.
Obviously all gifts are good (as long as you, like me, value wikipedia). And this is a big one. But it hardly qualifies as earth-shaking philanthropy. It's the gift amount Brin would be expected to give, I'd say. Obviously there's a lot of apples and oranges here; both of the numbers above represent "tied down" assets and not disposable cash, etc...
But shouldn't the extremely wealthy be held to higher standards about what they're expected to do with their charity? Why must it be news when someone like Brin does the equivalent of clicking on "Donate via PayPal".
I guess one good thing came of this though: lest I feel like a hypocrite, I went to Wikipedia and clicked on "Donate $100". So that makes me a better person than Brin, I guess?
