Visit wikipedia.com thoroughly. Look up numerous articles. Look at the article histories. Contribute to an article in a subject area you have some knowledge in. Look at entries you might expect to find in a traditional encyclopedia (e.g., "Germany") as well as those you might not (e.g. "emoticon"). Wikipedia clearly affords a level of participation very different from that of the traditional encyclopedia. How does this participation change the notion of "human knowledge"? Does it improve or undermine the encyclopedia as a concept? Why or why not? Be specific, using particular examples.
