Yeah I don't use FB either for lots of reasons. The data mining, the self fulfilling algorithm decisions about me, Zuckerberg being a total fuck wit, etc. I've seen FB do serious national damage up close and personal in a former job, so I hate the echo chamber and disinformation aspects. Also, the product itself sucks now. Except! The events feature, that is actual useful and I would consider signing up if I had more time to go out (maybe when the kids are older if FB is still a thing). I use Twitter as a topic reader, the lists feature is really good for building focused microblog feeds. I also share some lists with people I work with if I feel they should know more about what's going on in the industry. A private Instagram account turned out to be the most efficient way to share family photos. Yeah, it's still FB. I just set it to private and treat it like a shared album that specific people can access regardless of platform.
At least you get it. So many people I know are vehemently opposed to FB and "won't ever use it".... and post prolifically to Instagram. smh In fact, I used Instagram before FB bought it. It had the finest content discovery algorithm I've ever seen in any social media. It was Spotity-good at showing me content and creators that I just loved. When they dumped the algorithm and went with Facebook's "content from your top 5 loudest friends and nobody else EVER" algorithm, I dumped Insta. Became useless overnight. "...A private Instagram account ... Yeah, it's still FB..."
