I tend to agree, at least with respect to vast majority of potential Wkitree users who don't spend significant time working or editing family history, although they may be very good and very dedicated family historians and genealogists.
Until editing profiles is "what you see is what you get", there will be a ceiling on Wikitree's potential for me. I have found my family collaborators find Wikitree to be something they don't want to invest in learning. It simply takes too much time, effort and concentration to edit a profile even in simple HTML, particularly when family history is what fits into brief minutes between full time job and family. I sometimes would just love to make quick edits, but reading the profile on the editing page is sometimes just too much at midnight, when I might be slipping in my family history time.
While in my experience many mentors and others are friendly and available, "do it yourself" help is too many clicks away. And I confess I still do not understand categories and projects. It takes too many clicks to look for projects/categories which profiles I manage may fit. Even should I know of one, I don't understand how to bring them to the attention of project/category managers/members who may be interested in collaborating on that profile where I do not have the time or inclination. For instance, I manage profiles which would fit in US Civil War, US Southern colonies, etc., and would love to have project members collaborate but I don't know how to message them. I think the right hand of the editing page could be used better to encourage this kind of collaboration.
I love WIkitree, and the idea of Wikitree. It is still the best platform for me, and I am still committed to it within my limitations. But I find myself spending less time. But then, not everything is for everybody all the time, and that's fine, too
