Karyn Ritter's husband has a company called Doppleganger. Their first product is a virtual nightclub where you can go to hang out, talk with other people online, dance, flirt, and everything else a high-end nightclub has. Karyn showed me an early demo of the lounge, and I have to say it was pretty impressive -- and fun.

Karyn tells me a reporter writing about the site couldn't get anyone in the club to talk to him, not even the robot bartenders. "So, the software is very realistic," I said. "Yup," replied Karyn.
