It'll be all like "flying around for a bit" and "chatting with ridiculously well-endowed furry" and then it will go all meta, like "posting on Second Twitter, be right back", and so on and so forth, until the Second Universe collapses on itself in an implosion of self-referential timewasting.

I think you should be careful, this seems like one of those things you can bring in to being just by speaking it's name aloud.

right, like the time we said "It's only a matter of time before people start naming their children after their handle when they met" and the friend we said it to said, "oh [couple's name redacted] named [baby's name redacted] after her on-line name when they met." Part of me died, just a little.

it's only a matter of time before they've got a Twitter for Second Life.

Wow. I'm so crabbed and old that I can't even tell whether this concept is genuinely absurd, or only absurd to me in that "hmph, those crazy kids with their hair and their clothes and their rock&roll combos" way.
