Can you clarify the contradiction here as I'm still not clear what you intend to do. Part of the post reads, "Mutually confirming a match creates a virtual link between the corresponding profiles across family trees. In the future we plan to show these links in the trees and allow you to jump conveniently from a profile in your tree to another tree with which you have mutually confirmed matches, and we'll add other visual enhancements to allow navigation in a mega-tree of confirmed matches. Judging from the amazing pace of new confirmations that we are seeing (approx. half a million confirmations in the first 2 days since we introduced this), the users of MyHeritage.com are now building what could arguably be the world's largest family tree very quickly, by forming confirmed connections between the 680 million profiles in their 17 million family trees. We'll keep you posted on our blog as to the pace of growth of this gigantic mega-tree."
"It does NOT merge profiles, and it does NOT cause two family trees to become fused into one. We are against that. We believe that users on MyHeritage.com should remain the owners of their tree, in full control of their own tree, always able to export or delete it, and without anyone else coming unexpectedly to modify its data. MyHeritage.com has another competitor that is building a big tree by luring users into merging their profiles with other people.... There is no "single truth" and trees must not be forced to merge if there are differences of opinion, every user should be at liberty to pick what data they want to add to their tree, from the research of others."
People invited to my tree can update it. I am no longer the single owner. Yet your matching will never merge the trees in to one so that a match can reveal lots of other people in another tree, to my own. Matched trees and subsequent invited users will be a part of BOTH trees, not a single larger tree, requiring that the user then start updating both trees. Is that correct?
Forgive me for trying to be so clear it's just rather confusing. Contradicting your post, when it comes to family, there is only a single truth - people can't have a difference of opinion about an ancestor - you either are or are not related. I see what you are trying to ensure, control, privacy, etc. but Smart Matching seems to still only give you access to more/better data than what you might already have while preventing collaboration on a single tree of related parties.
