I just stumbled across [[The KnowledgeWeb]] on Recent Changes, and had a look at their demo, especially their demo search results (http://www.k-web.org/demo/search_results.html). It resembles "What links here", but goes beyond it.
I think it would be quite possible to have such a "view" linked from every wikipedia article. As brief contents, we could use the first (real) sentence of an article (that is, no table containing images, no language links, etc.). We could also display the first image of the article, if there is one. We don't have a "node type", though. (I tried to introduce flexible categories to wikipedia in the past, but would you listen to me? ;-)
Would there be, basically, interest in such a "smart browse" (or whatever) function?
