That's how I feel too. I'm not sure if it's because of Facebook itself, or just more about my personal growth and realizing that spending much time on social media in general was a waste of time.

I've found that I just care less what people are posting about than I used to, and I care less about posting my own stuff too. Would rather catch up when I see them next in person. And if I'm never going to see them in person, they're not really a big part of my life anyway.

Facebook's algorithm seems to get worse as time goes on too. It tends to show me the same old posts from around 20% of my friends and ignores what 80% of my other friends post. Maybe I'm technically wrong about this, but that's how it feels.
