I was just about to write a review of the new social networking launch, Geni, when I received my weekly issue of Family Tree Magazine's Newsletter -- and it said just about everything I was planning to say. Geni sports a super-easy user interface, but if you're into genealogy, a lot of questions will start popping into your head as soon as you jump in. See what Diane Haddad has to say in this issue.
Incidentally, even if you're not interested in learning more about Geni, you might want to take a peek because this is a great newsletter. And while you're at it, you might want to add to two cents' worth to the forum on genealogical pet peeves!
