Here's a hoax that persisted for weeks and was picked up by MSM articles.

One question is how to catch / force-verify new facts. A totally
separate one is how to make corrections stick / how to improve the
rate of awareness about updates in important information by people who
are relying on it. What do people think about maintaining a list of
external groups / works that rely on part of an article, or providing
an explicit 'update' service that makes it easy to get low-traffic
push updates to data about articles you care about?
Then there could be a standard way to cite / use an article externally
which involves a step of being added to this push process.
