Radar Networks coming out of Stealth

My friend Nova Spivak's company Radar Networks is coming out of stealth mode! They are launching Twine.com which is a consumer facing semantic web site.

I'm very curious to actually get to play with it as I've heard about it for a while now but he's been keeping the details very secret.
