Do you trust Wikipedia?

Some researchers at the University of California at Santa Cruz have created WikiTrust for evaluating every word on Wikipedia. It highlights text added by authors according to their past editing reputation. It works with a cached copy of Wikipedia so is not totally up to date. "Suspect" text gets deeper and deeper orange highlighting. It is an interesting idea, and may well be developed further and applied to other wikis. Could be useful in teaching students about Wikipedia and exposing more questionable parts and how entries are built up.
