Rootsy’s private social network lets you build your family tree online.  
[Social Media / Technology / Family]

If you’re one of those people that gets creeped out by social networks, but want to keep in touch with family, Rootsy is for you. You can build out your family tree (simply and easily, mind you!) and add accompanying photos/videos to help tell the story. Your story. I’m into this. Disclosure: I’m friends with one of the founders, Cezary. (But he didn’t ask me to write any of this!)
