Rufus Griscom conquered the high-brow sex market with Nerve.com. Then he went on in December '06 to start Babble.com, a site for babies. Or about babies. Raising babies? Eating babies?

Whatever.

Apparently, Babble is outperforming their expectations – half a million visitors a month, and about to be profitable! – leading the Nerve epicenter to begin work on a brand new project, we hear. Next up: The environment. Saving it? Destroying it? Explaining why it's the middle of October and 75 degrees outside?

Who knows!

Actually, Nerve chief Rufus Griscom did give us a hint when we called to pester: It's "more focused on green lifestyle than politics." There are two contenders for names (he wouldn't share either), and an editor has been chosen (also not something he's sharing). But look out for it in mid-November, when Al Gore gets a new homepage.
