U.S. users are leaving Facebook by the millions, Edison Research says

By far the biggest factor that had me stopping checking Facebook, and indeed LinkedIn, is number of utterly fictitious notifications they generate. There was a time a few years back when that red dot made me drop everything to check FB, but these days it’ll be some completely bullshit message they’ve made a notification out of. Feels like they got greedy for my attention and killed the golden goose there. I check it about once a day now, and in the browser not the app. If the notifications were still meaningful I’d probably still have the app and all the metadata that sent them.

It really feels like some companies like Facebook are flying blind by using A/B testing everywhere and ignoring the long term effects of the changes they do.

Isn't A/B testing pretty much going to behave like a steepest ascent hill climbing? At each micro decision point you take what looks like the 'best' option but that means you can get stuck in local maxima?

This is interesting but I don't think I fully understand. Do you mind dumbing it down for me?
