Re: F8 ?
"Hello, we're Facebook, and we've decided to use an abbreviation for our name that, coincidentally, is pronounced 'fate'. Have we mentioned that we're run by megalomaniacs?"
(Obviously the correct abbreviation would be f6k, by analogy with i18n and the like. Then we could write things like "that's f6k'd up" and "oh, you've been f6k'd".)
