Ancestry has added some cool things to the public profile you can create on the Community tab. For example, when you add surnames to your profile, it will search for other members with similar interests and link you to their member trees. You can also build “genealogy karma points” by listing services you’d be willing to provide for other members, such as taking headstoneÂ photos at local cemeteriesÂ or of local buildings or other landmarks, visiting a local courthouse or library, etc. It’s a fun way to connect with other Ancestry members and to let potention cousins find you.
You can learn more about it in David Graham’s post on the Ancestry blog.
