I really don't like Zuckerberg and expected to disagree with him (especially about maps, everyone gets maps wrong (especially especially on computers) but this isn't a map of the earth.) This sounds right to me. Every time someone says we've figured everything out they're always wrong. There's always more to understand.

I don't think Facebook legitimately adds value, I think it's entirely parasitic. But we haven't discovered everything there is to know about talking with each other.
