Facebook is filled with billions of people I have no reason to speak to, ergo its network effects for me are zero, and its value to me is zero. Other services have similar zero or negative value, and hence I don't use them either. As much as some around here would like to believe that network effects are a moat that effectively allow social media to be immortal, experience has shown that not to be the case. Facebook is dying a slow, lingering death. It is not the place you go to find trendsetters and people of import, but, at best, to go check up on grandma. Facebook will die when grandma finally kicks the bucket and there isn't anyone to replace her because they're all on Discord.
