Answers.com links to Wikipedia

Now that Google has linked to Anwers.com, and the latter is linked directly to Wikipedia, we have a situation where it becomes advantageous for scholars and others to provide content for the free, user-updatable encyclopedia. This in turn makes it likely the encyclopedia will become not just the largest (it is already) but perhaps even the most authoritative. Talk about a rapid climb up the 'fitness landscape' (see link).
