I've always wondered about the people who do this. Do they realise what the purpose of a headline is? It is to encourage the reader to invest time in a story. Usually that involves summarising it down to the bare minimum while still making it interesting. I suppose I could have written "You'll never believe how this USB gadget cures holiday nightmares!" but that does feel like click-bait. I considered writing "A gadget which is powered by USB-C cures the common effects of mosquito bites in a sample size of 1" but that felt needlessly verbose. So, my question back to you is this - how would you rewrite the headline? What short sentence would you use which maximises the twin constrains of accuracy and brevity?
