Genealogy tool Familybuilder (formerly known as iFamily), has reached an important milestone -- 16 million profiles built within its network. Having launched a year ago today as a Facebook application, Familybuilder has spread to a number of other networks like Bebo and Orkut.
This has allowed Familybuilder to take a similar approach to other services like LendingTree, which have taken full advantage of multiple social networking platforms. With an internal application on some of the most popular social networks, Familybuilder is able to leverage the far stretch of these networks, as well as the existing relationships that its users have already built. While it's not entirely common that the bulk of your family members will be on any of these social networks, Familybuilder has become a useful tool for connecting with family members that are (we all have at least one cousin on Facebook!).
