As part of some discussions with Jim Maddock (see his recent thread
<https://lists.wikimedia.org/hyperkitty/list/wiki-research-l@lists.wikimedia.org/thread/INT2D2XGJ4YO2NVYBNKOOQMVI6OXKG32/>),
I started a meta page to catalog some of the many natural experiments
<https://en.wikipedia.org/wiki/Natural_experiment> that impact the
Wikimedia projects. I've seeded it with some examples (censorship,
Wikipedia Zero, lockdowns, Public Domain Day, new data centers, etc.) but
am certain that there are many more out there. If folks on this list know
of other examples, please edit the page below boldly or respond on thread
and I'll migrate examples onto the page.

Best,
Isaac
