Congratulations to them both as well.
You don't know them, I'm fairly confident. I don't know them. Almost no one here knows them. The single and only reason this has any relevance is because of Facebook, IPOs, from which a natural discussion is pre-nups, etc. Or are we to all pretend that we're pals?
I don't understand some of the materialistic comments (prenups etc.) on this thread. Zuck marrying his long time love is a beautiful blessing. PG, I'd met Zuck after you had invited him to your startup school 2007 and since then have interacted with him. He also kept his word on followups he'd announced during his talk then. He is such a humble person despite all his successes. I'm so happy for him.
Congratulating on his FB or Twitter would be more effective :)
