Essay by TimBernersLee about why AtomWiki:UniversalResourceIdentifiers should remain constant and prevent Wiki:LinkRot.
MeatballWiki itself is not immune to Tim's criticisms:
Some WikiEngines allow you to use a URL that looks like static one: eg:
http://wiki.beyondunreal.com/wiki/Recent_Changes http://diveintoosx.org/
or one that does not include the script name:
http://css-discuss.incutio.com/?page=RecentChanges
This takes only a very minor amount of tweaking of browser parameters and environment variables. There is (probably) a patch for UseMod for this -- if not, ask TarQuin about how UnrealWiki does it.
We also delete pages - rather than leaving redirects - when we rename or merge pages.
