WikiWord Vs Search

Does it make sense to drive all your writing from WikiWord-s, if Search Engine-s become more available to everyone (consider Devon Think, etc.)?

I still think it makes sense, because it helps you organize your thinking, having a Shared Language. This is obvious in a TeamWiki environment, but it's even true when sharing with yourself in a Private Wiki (you're sharing with your Future Self)! (Tags Vs Free Text)

Update: this Shared Language could, in theory, work in other apps as well: AppWiki.
