Reminds me of some thoughts I had on how Bill Gates is the richest man in the world, and yet you or I can use an iPhone, while he, despite his wealth, is stuck with clunky Windows Mobile.
Reading his writing here, I have the same reaction to when I read the leaked articles of his on Slate, which is a sort of soft surprise that he's one of the few people online that I've read who has some sense of grammar and sentence construction. He writes like somebody who knows how to write.
It surprised me then and surprises me now, because there's some reputation of Zuckerberg as a sort of clueless cro-magnon whose web site is an ugly, lame waste of time, and while I disagree with the latter very strongly, I still like reading the posts he makes and getting the feeling that he is, in fact, a very smart person.
(I also love the fact that he's the man whose at the age and fame level to really be able to use Facebook and become a celebrity-hounding fameballer, but hasn't taken advantage of his success whatsoever. The guy just has a very honest feeling to him, and that reflects in his site. I like that.)
