Nope, we're not liveblogging Facebook's messaging-related event today, since we're en route to the Web 2.0 summit -- and a new email service isn't really our bag anyway.

And whether our own Josh Topolsky will get mobile, social, and Four Loko with it after last week's podcast rant? The floor is yours.
