Word magic is the art of inventing cool names, names that stick, names that say more to the individual listener than the simple expansion of the term (or terms, if a composite).
Unfortunately, the attempt to build a PatternLanguage brings with it the risk of uncontrolled word magic. Cool names are being invented for no reason at all. And worse, often a ShallowPage is created to remember the cool sounding name. But without actually considering whether the name is useful or not.
Examples (just search for "^Wiki"): WikiWalking, WikiWeaving, WikiMentor? (given that we alread have a WikiMaster), WikiMutants, WikiClone, WikiEngine, WikiMass... Sometimes I think I see what the original author aimed at, and sometimes the pages were filled with interesting content that might have been more useful on a page with a different name.
I'm proud to say that I think I started at least two of those pages :) It should be noted that I created them because either the current name was flawed in some way (I think WikiClone should technically refer to something with a similar feature set as WardsWiki, and many WikiEngines have critical innovations), or because I thought the concept (not just the wording) was distinct and didn't really belong on some other page (as with WikiMass, which was created because there was a comment on this concept on CategoryFilteredRecentChanges; I feel that substantial discussion (rather than metadiscussion) never belong on category pages).
WikiNow is imho another candidate. I also prefer WikiSoftware to WikiEngine. Maybe we should create a CategoryWordMagic? to critically reduce the language we use. BarnRaising is really something different (agree with Sunir), also because it is a metaphor for synergy which is fundamental for social phenomena and online communities. -- HelmutLeitner
Programmers spend a lot of time naming things (see Wiki:CategoryNaming) and often try to create good word magic with their names. People who create wiki pages also spend a lot of time naming things, and often try to create good word magic with their WikiPageNames.
