I deactivated my first account 8 years ago, but got back on to re-connect with my old pals and acquaintances from back in the day. For that reason, it was fantastic.
After another year, I realized that I can't actually say ANYTHING interesting on this platform without offending someone. There's a lot of variety in my crowd. I have the sense IRL to know that not everything is for everybody, but that doesn't matter much on Facebook unless you want to spend hours and hours hand-crafting subsets of your friends for different topics (I don't). And I have zero interest in posting selfies or status updates of what's going on in my life, so that made the platform exceedingly boring and a waste of time for me. It's a shame, because it does work really well for "connecting" with people (in the shallowest sense of the word).
Online we're all on teams. If anywhere in your post history you indicate your on a different team then we need to say mean things to each other.
In real life I have very liberal , very conservative and somewhat indifferent friends. I've also dated a variety of folks with different political leanings. I've largely stepped back from social media due to this. Why am I going to get into arguments with people I don't even know ?
If you want to connect with people, I suggest meet up groups. It's very easy to make friends you can actually hang out with. I would say to prioritize doing things you want to do. Like I'm heavily into tech talks , so I attended a ton of those.
I'm fairly optimistic next year the vaccine will be out and things will be somewhat normal.
