Sometimes it's interesting to read policy from other wikis that are currently successful and growing and see how they differ from WP.
eg: http://tvtropes.org/pmwiki/pmwiki.php/Main/ThereIsNoSuchThingAsNotability or: http://tvtropes.org/pmwiki/pmwiki.php/Main/WikipediaUpdater (considered an antipattern on tv tropes!)
Addiction warning: These are links to TVTropes. http://tvtropes.org/pmwiki/pmwiki.php/Main/TVTropesWillRuinYourLife
(Isn't getting people addicted to reading and editing a *GOOD* thing, from a wiki POV?)
sincerely, Kim Bruning
