The majority of the feed was what looked like irrelevant spam, ads or political arguing. It has essentially no positive value anymore so I deleted my account.
Not only that, but I've actually experienced first-hand, and witnessed many of my friends experiencing depression and anxiety from the constant scrolling. The 'desire to be seen or heard' factor really plays in to an overall sense of toxicity and negativity that there have actually been a number of psychology studies on.
Overall, I find, contrary to say, HN, which I still spend too much time on (but mostly when I'm bored at work, ha), there is no bar of quality on Facebook. It's a cesspool of humanity's worst sides, especially if you consider the privacy violations of the medium itself.
In fact, it's actually becoming a faster and faster race to the bottom. (Can we all remember this year of 2018 started with 'Tide Pods'?)
Even Reddit has some quality control.
I've yet to bring myself to delete the account, since I get occasional messages I care about and it's convenient to lookup someone's email you've lost. I would if that wasn't the case.
I've uninstalled the app, but that's because it was a huge battery drain.
