Criticism of Wikipedia is often relegated to outside the system itself, due to the possibility of censorship or banning if an administrator decides they don't like what you say.
There's plenty of fluff hyping Wikipedia on Wikipedia itself so there's no need to include sites dedicated to praising Wikipedia (if there is such a thing), however Wikipedia does have some positive points and well-written articles get included.
Here's some so far:
The Guardian: Can You Trust Wikipedia?

The Register: Who owns your Wikipedia bio?
http://www.theregister.co.uk/2005/12/06/wikipedia_bio/
Article criticial of Wikipedia.
"It's also like playing a game in the sense that playing it has no consequences. If something goes wrong, you just restart. No problem!" -Jimbo Wales on Wikipedia
"Wikipedia as a massively scalable, online role-playing game, or RPG. Players can assume fictional online identities - and many "editors" do just that. And drive-by shootings are common."
The Register: Wikipedia: magic, monkeys and typewriters
http://www.theregister.co.uk/2005/10/24/wikipedia_letters/
Mostly letters from previous Wikipedians who decided to stop editing.
"At first I thought Wikipedia was a great idea and started writing about the subjects I know with an academic take on them. [...] In the end I couldn't recognise my articles after about a week, and a few months later there was nothing left of them, having sufferd zillions of re-edits, irrelevant sentence adding and re-writes due to NPOV actually meaning MPOVNSE -my point of view, not someone elses. [...] I just gave up and let the idiots who THOUGHT they knew something about the subject or those with a vested interest in making things look good take the helm."
Why Wikipedia sucks. Big time.

Blog. Updated frequently. Good general criticism of Wikipedia, but also gets into the nitty-gritty of it (i.e. discusses specific articles). The author is a librarian.

Wikipedia and the Future of Social Computing, by Ross Mayfield
http://www.kuro5hin.org/story/2004/12/30/142458/25
A paraphrase of a speech by Jimbo Wales, pro-Wikipedia stance but accepting that he is the unelected "constitutional monarch" of Wikipedia.
Has some interesting comments.

"The present generation of bloggers seems to imagine that such crassly egotistical behavior is socially acceptable and that time-honored editorial and filtering functions have no place in cyberspace. Undoubtedly, these are the same individuals who believe that the free-for-all, communitarian approach of Wikipedia is the way forward. Librarians, of course, know better."

"In general, Wikipedia is a game. Nobody making policy decisions is getting their knowledge of the Iraq War, stem cells or Social Security from Wikipedia, so in the grand scheme of things, it doesn't matter what Wikipedia says. But when they start writing biographies of living individuals, that can have real-world consequences on a person's life. It's not a game to those people."

"Wikipedia should not be cited in the media nor anywhere for support because it is no different than quoting various anonymous sources who have no knowledge of the topic or who have fibs to spread about the topic."
