1) More work at
http://en.wikipedia.org/wiki/Wikipedia:Verifiability/Proposed_revision
:
What, you ask, is verifiable information? [[Wikipedia:Use common
sense|Use common sense]], but if you're unsure or are involved in a
dispute, read [[Wikipedia:No original research]], [[Wikipedia:Reliable
sources]], and [[Wikipedia:Try to verify]].
2)
http://en.wikipedia.org/wiki/Wikipedia:Try_to_verify is evolving
based on edits and comments on the listserv.
3) A problem I've noticed is that [[Wikipedia:Citing sources]] is
morphing from a style guide to a policy guide. The "When to cite
sources" and "Why sources should be cited" are not style guide
sections, but rehashes of [[Wikipedia:Verifiability]] and such -- I've
copied over the "When to cite sources" section to [[Wikipedia:Try to
verify]] which tackles just that issue (in a hortatory manner).
