Thanks for your contribution to this discussion, it's helpful to have actual numbers.
There was a mixed metaphor that popped out to me in your comment (and I hope pointing it out doesn't break HN guidelines around tangential annoyances):
> I made my bed and slept in it, so I have no axe to grind
It reminded me of something George Orwell wrote in 'Politics and the English Language':
> A newly invented metaphor assists thought by evoking a visual image, while on the other hand a metaphor which is technically ‘dead’ (e. g. iron resolution) has in effect reverted to being an ordinary word and can generally be used without loss of vividness. But in between these two classes there is a huge dump of worn-out metaphors which have lost all evocative power and are merely used because they save people the trouble of inventing phrases for themselves. Examples are: Ring the changes on, take up the cudgels for, toe the line, ride roughshod over, stand shoulder to shoulder with, play into the hands of, no axe to grind, grist to the mill, fishing in troubled waters, on the order of the day, Achilles’ heel, swan song, hotbed. Many of these are used without knowledge of their meaning (what is a ‘rift’, for instance?), and incompatible metaphors are frequently mixed, a sure sign that the writer is not interested in what he is saying...
> By using stale metaphors, similes and idioms, you save much mental effort, at the cost of leaving your meaning vague, not only for your reader but for yourself. This is the significance of mixed metaphors. The sole aim of a metaphor is to call up a visual image. When these images clash – as in The Fascist octopus has sung its swan song, the jackboot is thrown into the melting pot – it can be taken as certain that the writer is not seeing a mental image of the objects he is naming
