The end of Facebook couldn't come soon enough, but we've been reading headlines not unlike this for around a decade, yet still its malignant tumour in the lungs of the Web grows, sucking the air out of all good things.

Despite losses in the youth market (not only in the UK), as the article notes, Facebook has deep pockets and is metastasizing at a frightening rate. Instagram and WhatsApp are only the most prominent recent growths, and no doubt far from the last. Also, the main tumour itself is still evolving, backed by development funding that staggers belief. It would take a lot to cure us of this awful thing. On the optimistic side, however, Metcalfe's Law works just as well in reverse as going forward. Networks can grow exponentially, but they can shrink just as fast. Perhaps these small losses will be the start of a cascade. Let's hope so.
