It seems this word is used primarily recently for Internet groups, e.g. a Wikimedia meetup. I assume because generally Internet-group users don't meet face-to-face, compared with businesspeople. I'm sure I said "Let's meet up" 20 years ago, but I'll add some citations next time I'm online to back this up. --Jackofclubs 11:56, 6 December 2008 (UTC)
