How has Geneweb worked for you? Is it straightforward enough to use if you are somewhat technical, or do the “wizards” need to have a solid understanding of OCaml to make it worthwhile?
My daughter has been interested for years in delving into our different familial trees and has extensive records on paper and in various digital formats. She isn’t overly technical but could be taught to use a web interface if she’d gain value from the effort.
In my humble opinion as an amateur genealogist, after a year or so with paid services (Ancestry, Myheritage) I find there is really no good reason not to use a combination of Wikitree and Familysearch, both free, if we ignore DNA tests.
Especially familysearch allows private profiles, no need to share. Wikitree has a policy of "do not add living people", but it is possible to do and Ive done it for close family.
Yes, this means sharing fairly freely, but I do not see a reason not to. Unless you want a fantasy tree, sharing your tree will make it higher quality. We all make mistakes here and there.
Wikitree especially requires you add sources to your work, which might feel odd for a personal tree of course.
