Some questions to start.
- How has notability changed over time?
- Ditto for verifiability and other scope questions, but focus on N.
- What articles with over 100 contributors, or 200 revisions, have been deleted without transwiki?
- Were they saved anywhere else online?
- What is "all the information" that is useful to researchers and readers? We are well beyond the guidelines of a traditional encyclopedia.
- What subject-specific encyclopedias can be compared, and what are their guidelines?
