How about this for an experiment: turn off article creation _and_
deletion for a while? Freeze the table of contents (not that we have
one)...
So that all anyone could possibly do is to edit existing articles?
It would force everyone to pay attention to the articles that exist
already, and with 857,833 of them you'd think people could find
something worth their attention.
With deletion being impossible, AfD would become unnecessary... as
would DRV. So, that should make one faction happy. On the other hand,
there would be no opportunity to add subtrivial topics. (Or trivial
topics, or significant topics). That should make another faction happy.
