Hmm, interesting. Ann, Jillaine...
Do you think that listing the kids/siblings in the bio/notes section, instead of entering it (and making it searchable) via the site's structured data is speeding up the overall wikitree process, as a whole? Of finding and joining up all the disconnected mini trees, and finding and merging all the duplicates, and fixing all the data quality problems?
Intuitively, I would guess not making profiles (rather lists of notes) or making partial family profiles but omitting breadth would be slowing down the process (i.e. the good work) down... and potentially very significantly given the scale of the site. Curious how I might be misunderstanding what's working for you.
