Wiki philosophy is in development. It will poll wikipedia (or any wikimedia project) and get and maintain a list of articles that don't eventually first-link to a specific page. (By default that don't link to philosophy).
The first-link philosophy phenomenon is popular online.
The popularization of this phenomanon is likely do mostly to this XKCD comic.
Mouseover text: Wikipedia trivia: if you take any article, click on the first link in the article text not in parentheses or italics, and then repeat, you will eventually end up at "Philosophy".
It does, of course have a wikipedia page. Wikipedia:Getting To Philosophy
Like many things, millions more references are on Google.
