How to write about things like [[Citizendium]], [[Conservapedia]],
[[Veropedia]] - things that were notable at the time and got lots of
press coverage and hence articles, and which readers may well want to
read about into the future - but which have fallen out of notice and
so their decline (and, in the case of Veropedia, death) got no
coverage and hence we can't answer the reader question "so, whatever
did happen to X?"
(Anyone who wants to reply saying "Citizendium is alive and well and
will rise again!" or similar needs to check the most recent
WP:RS-suitable coverage from 2011:
http://arstechnica.com/tech-policy/2011/10/five-year-old-wikipedia-fork-is-…
and particularly the comments, where people have never heard of this
thing and in two weeks no-one even defends the project.)
