Some of these were created with links to them, and then the source pages were changed... and I think it's a real pity that my WikiIsland from the old wiki didn't survive the port. Oh well, some HistoricArtifact?s are destroyed by the ravages of time, I guess...
And help give some orphan pages a home!
I want to reiterate my position from the last time this "issue" came up, on OpenForum under "coming of age." The Wiki:WikiIceberg is a normal phenomenon that happens on all wikis without causing any problems. (In fact, the only reason ours is so small is that I took the May 2001 software migration as a chance to tidy it up a bit.) Orphaned pages do not interfere with normal use.
I don't think it's necessary to warn authors about this, or that it will keep islands from happening. Nearly all the orphans listed were once in actual use, but were replaced by other pages or otherwise fell out of favor. (That, or they are software artifacts from the very first PhpWiki installation on valis.st.)
It's a feature, not a problem, that such pages become orphaned and hidden when they are no longer used. Also consider: no page is truly orphaned unless it also has no backlinks. Even then it will show up in text searches when appropriate.
I'd like to add my two cents to this issue--invoking my OriginalWikiWhore status, if required:
WikiIslands are not bad. They are interesting both in concept and often in content. However, this does not mean they get inherently more cool by "connecting" them to the main connected subgraph of the wiki. If there are links that should belong on said island, then by all means, add them. Marking them all as WikiIslands, though, downplays their coolness. Finding a WikiIsland should be like stumbling across an interesting view when utterly lost--you're glad to see something interesting and new and the fact that you're not sure exactly where you are or how you got there just improves the sensation. Please, don't take much of the fun out of RandomPage? walks. Also, allow these pages to keep their title, as labeling them WikiIslands removes their WikiIsland status. Sad, isn't it?
