I know you’re sounding edgy, but the answer is “a lot”. My entire family and I have probably a good 30+ friends that are active (weekly or more) on it.

Businesses, so many businesses have just a facebook page, no website or anything else. Want to know what or when the next band is playing or the nightly special, check facebook. 🤷

Senior citizens

People selling lawnmowers and TVs from 2013 that still work.

Anything that has to do with local event information.

I see several people claiming they just use it for marketplace, or whatever it’s called.

Most of the internet connected world. Allegedly they have 3 billion monthly active users.

My entire small town exclusively uses Facebook for everything from local gossip, to selling stuff, to even hooking up. All the businesses use it and the only way to get updates on local power outages or emergency notices is through it as well. I don't use Facebook so it is a bit annoying.

Our parents. My mom is addicted, spends every spare moment endlessly scrolling. I tried for a while to get her off but you can't help someone who doesn't want to be helped. No shit she spent 10 straight hours on it once. Didn't move at all, she is their ideal consumer.

Approximately half the population of Earth is on it on a monthly basis.
