Edward Winkleman's advice:

Back when I lived in Washington DC, the Congressional candidate whose campaign I worked on explained that in politics you meet so many people you never say "Nice to meet you" when working a crowd. Odds are you'll say that to someone you had previously met, but don't recognize, and they'll feel insulted. Instead, you say "Nice to see you," because that covers both the folks you're meeting for the first time and those you've met before.

This is good advice. Some time ago, I was lucky enough to be able to have a chat with secretary of state Condi Rice. "Good morning, madam secretary. So good to meet you," I ventured. "Actually we have met before," she responded. Which is why she's secretary of state and I'm an addled blogger.
