My guess is that FamilySearch will have a lot of partners in the future. Right now in addition to the existing partnerships, FamilySearch is recently added Famicity.com. Here is an introductory video for the new partner.
There is another video linked from their startup page. Here is a quote from the recent announcement by FamilySearch of the partnership.
Famicity is an intuitive, app-based tool. It is simple to use, and encourages more communication between family members. Stories, photos, and videos are easily added and conveniently time stamped. It also allows users to give other family members permission to add to a story.
Today, families are spread out geographically and lean heavily on technology like social media to communicate and share family moments. Websites like Facebook aim to bring families closer together; however, these websites can be overwhelming and lack family focus with all the content being posted by a growing subscription of friends. Famicity is private and allows invited family members to focus on sharing and preserving family-focused content.
Created from the beginning as a social media platform, “Famicity understands the needs of FamilySearch.org users and that's why we've reinvented social media for each and every member of a family to bond, grow, and celebrate their lives privately and securely,” said Famicity co-founder Guillaume Languereau. “Famicity members can already create their family tree on their own. This partnership makes it even easier for FamilySearch members to sign up with their account and automatically upload their family tree into Famicity to start an online family reunion in private.”Presently, the program is free.
