>Personally, I think for 90% of the articles, Wales does a decent job as the final gatekeeper,
Which only indicates that you haven't looked at the actual content of Wikipedia very closely. I have. Yes, there are many good, usable articles on it. There are also millions of "junk" articles, thousands of hoaxes, tens of thousands of people being defamed in their biographies, hundreds of thousands of people glorifying themselves by writing their own bios (against Jimbo's own rule), and various other abuses. Some are repaired quickly, some sit there for years. And there's no way to tell if an article is valid or not, except by checking the references very carefully (which few people do anyway--Wikipedia is a lazy man's reference). Wales does no "gatekeeping" at all, he is purely a figurehead at this point.
What I really don't get: why do people worship him? He's one of the most inadequate leaders of a major online movement I've ever seen.
