I suppose like most of us, I am a little curious about my family history, but not enough to spend time or money researching it. That’s where Geni.com comes in.

Most of you probably know it, but just in case check it out. It’s a Wikipedia type site where members of your family fill in the genealogy tree. It’s only as good as the family memory, but that’s usually as good as it gets from an accuracy perspective.

The site is incredibly viral. I just filled in the name of a few relatives who are then invited to take a look at the tree and a few days later the tree had over 100 detailed entries.

I am not sure what business model they are going to implement, but as a user it’s a lot of fun to use and see your family tree grow with no effort.
