I would have much preferred something like this to be the summary: "WHO reports that tuberculosis, gonorrhoea, klebsiella, typhoid, syphilis and diphteria are becoming resistant to antibiotics." A couple of sentences quoted from the article would also be fine.
I think that in its role as a link aggregator, Boing Boing should add some value to the link: a note from an editor, an informative and useful summary or excerpt, perhaps a comparison to something else on the subject. As it is, the entire presentation of this article on BB - the headline and summary - provide less information than the headline and summary in The Guardian, which is pretty click-bait-y to begin with. This is just bad form.
