I noticed a few wiki sites were hacked on the wknd, the hackers managed to created/upload spammy page with , h1/kw-kw-kw, random text with plenty of kw's.
The pages on the wiki's dominated the serps, position 2/3/5/7 in one sector alone. Today, the link is still active in Google, however, the sites have a notice saying they have temporary shut-down the site due to spam abuse.
Wiki articles are often quite good imo, the editors know their stuff. But the're also faced with the reality that a wiki article is usually the best of the rest. Someone that knows his stuff and is dedicated will write on his own website.
The reason that the best of the rest articles are now rated as the best by Google is Google's current anti-spam campaign and Wikipedia has massive TrustRank. Same situation on MSN at the moment.
I'd like to see a thread (I'm sure it's there somewhere) about the question: is Google (especially) exaggerating it's emphasis on anti-spam and if so, why?

Doubtlessly some are, but which.. Now people came up with something called degrees etc to _limit_ the option of morons pretending to know something. In the end WP (and Google) has to learn there is some worth in qualifications also outside the Googleplex .. unless you want to have your future operations done my docs trained on Wikipedia.
