I honestly can't answer that but I cold-turkey'd my fb account about 2 years ago and I will never look back. You have to be a god damned fool to keep them posted on your day to day life.
Absolutely the biggest form of hyperbole I've ever seen in my entire life, bar none.
Seriously though, some people use FB sparingly once or twice a day. Some people actually make money from FB or use it for marketing.
There are a lot of people that get more out of it than making snarky election posts.
I personally love Facebook. I keep in touch with family I can't see often. They get to see my daughter as if they live near us.
I've engaged with people I would have never engaged with all because we have mutual friends, and end up growing friendships out of it.
I get to share things I find interesting, my thoughts, my feelings. I get to see a deeper side of my family and friends whom also do the same.
Look if your family and friends suck and all you see is "I had a bologna sandwich today" repeatedly, or that's all you can contribute, than take a look at your life and choice of peers, because using Facebook or not doesn't make or break them.
That's a little much. There is one important usecase that I have: messenger. A lot of people (even the ones that I regularly meet) prefer to use messenger and that's the only reason I am sticking with it for now.
