That is great for two reasons: 1) some profiles were improved, and 2) the categorization served a good purpose.
When I first started the Ayer Name Study, someone wanted to participate and asked the simple question, "how can I help?" I realized I had no systematic way of answering and I thought it would be really useful to have lists of profiles needing sourcing, bios, adoption, cleanup, etc. As I started setting up the categories to make the lists self-populating I realized it would also be useful if the categories were setup consistent with other projects so as to leverage their work and possible collaboration. So, for example in addition to being subcategories of the name study, the ANS US unsourced is also a subcategory of the United States Unsourced Profiles of the Sourcerers; the ANS Unconnected is also a subcategory of the Unconnected Profiles of the Connector project; and the ANS Bio Needed is also a subcategory of the Needs Narrative/Bio of the Profile Improvement Project, etc.
I am also trying to do something similar for sources, tying into Rick Pierpont's Source categories but have not done much with them yet.
