Most large public wkis are “Wikipedia clones” to the extent that many of them use the same software/wikitext standard (MediaWiki), article naming conventions (which allows guessing the name and linking to an alternately-hosted article by simply switching the InterWiki prefix) and/or licensing (allowing for both mirroring and for sharing derivative versions)
The easiest way of supporting such clones today is probably donating to promising efforts (many of these now exist, albeit with varying levels of compatibility) and supporting CreativeCommons, who manage the underlying legal infrastructure making comprehensive “clones” possible in the first place.
