As a cost-saving measure, BBC Nature (bbc.co.uk/nature) gets its listing pages about different species of animals from Wikipedia. That then forces them to implicitly admit that Wikipedia isn't a reliable source (see excerpts from the BBC FAQ below).
What's BBC's suggested fix for spreading possibly inaccurate information to readers of their site? They suggest that experts go fix Wikipedia.
While this is understandable from a money-saving perspective, the BBC is being penny wise pound foolish: they're staking their reputation on Wikipedia.
