How is this different from what the Church of Jesus Christ of Latter-day Saints is doing?

The LDS Church (Mormon Church) also collects family trees for inclusion in its "Ancestral File." This file contains approximately 15 million individuals and is accessible at the Family History Centers of the LDS Church. The World Family Tree differs from the Ancestral File in the following key ways: • Access from home -- You can access the World Family Tree from your own computer. • More information on living individuals -- The names, genders, and family links of living individuals are published in the World Family Tree. In the Ancestral File, you can only access information about living individuals who are members of the LDS Church. The names of non-LDS living individuals are replaced with the word "Living," and no one can access any information about these individuals.  more
