Network effects drove FB growth. My friends were posting interesting stuff on FB, so I needed to join FB. Then my friends started posting stuff twice an hour from their phone, so I needed to check FB twice an hour from my phone. Reverse network effects undo that growth. First slowly, then seemingly all at once. My most influential and interesting friends rarely post on FB anymore. Most of my ordinary friends are still there, but they only post once a week or once a month. So I've deleted the FB app from my phone and now I check it a couple times a week from my laptop instead of a couple times an hour from my phone. It's like Gresham's Law for social networks. Bad actors drive out good actors. A falling signal-to-noise ratio is a vicious cycle that drives out signal and attracts more noise. FB overreached in driving engagement, and it's backfired spectacularly. The FB brand is damaged and young people are embarrassed to use it. Reverse network effects will remorselessly undo what network effects originally built.
