I've been Social Sober for 20 days now. I didn't delete any content from FB, since I had been using a fake name on there for 5 years. I just deactivated the account and haven't logged back in since.
I honestly haven't noticed much of a difference in my life. I still work all day, come home and watch Netflix or play my Switch.
It's ok to not "know" what's happening. Just do it!
I did the same with my facebook account last fall. I haven't missed it either. I admit I still use instagram and messenger though. I think most people on my facebook list had pretty much stopped using it regularly anyway, it was basically all ads by the time I left. Twitter I never really used to start with, its primary use-case for me is I'm walking around somewhere and something's going on and i search Twitter to see if someone who knows more about it than me has mentioned anything. Although even that use-case has gotten pretty hit-or-miss recently.
