Here's an interesting take on wikipedia: Was it just a fad?

The article says that Wikipedia action is declining: fewer accounts being established, fewer edits happening, etc. Maybe this is a plateau of sorts? The thing has to top out at some point, right? Though, I don't think this means it qualifies as a "fad." Here's another possibility:

"The problems with Wikipedia could also come down to an increasingly large schism in the site's community, with two groups at odds over what information should and should not be included.

Those known as the "deletionists" seem quick with the delete key and have high standards for "notability." However "inclusionists" disagree, saying that articles shouldn't be deleted quickly because they may be expanded later, pointing out many articles are written over several edits."

This debate seems to define Wikipedia. That is, it's not a problem to be gotten over - it's the thing (aporia?) that creates the text. It's the source of all that is interesting on Wikipedia.
