My worry here is that sink holes are going mainstream. The BBC included a video and if you look at the 'related video/audio' section to the right, they've got loads more sink hole-related videos and underneath the article are more links to articles about sink holes.
It's only a matter of time before the BBC starts blaming sink holes on climate change and then the fun will go out of it completely. Besides cow attacks, my specialist topic is going to be "car attacks house" stories, that's suitably unsettling and they'll never blame that on climate change.
