In the 'Wheel of Time' series, what is the game of stones? was answered by Teknophilia with:
It looks like Robert Jordan said that it was made-up game, but that is was meant to resemble GO.
He then cited wiki.answers.com as his source for the claim, and got four upvotes as a response. Is this really acceptable? Words from the author is indeed a great answer, but only if it comes from a trusted source. An anonymous wiki user hardly qualifies as a trusted source.
Should we downvote/flag as low quality answers with poor sources?
