I'm married but the concept of dating in this modern world is terrifying to me. First thing I would do would be to lookup a woman on social media to see if she's one of these crazies.
I overwhelmingly agree, but disagree in one regard; there is some signal in the scream of the noise and in not engaging whatsoever you miss that sliver of signal, which can be very important events in friend's/family member's lives they've chosen to document there, or maintain some sense of contact with people who are now geographically distant, etc.
Overall their effects are indescribably negative, simply due to how they effectively game people's innate insecurities, but they do have 1 to 2 uses that do improve the life of a private individual.
I feel super passionate about addressing the existing toxicity of existing social networks and making something more positive and uplifting - preserving what you call the "signal".
I launched something recently on HN about what I've been hacking on here: https://news.ycombinator.com/item?id=21771456
