Personally, as someone who hasn’t had a FB account for well over five years, it’s super weird to me that you need it to “keep up with family and friends”. You’re using a data harvesting, advertising, and propaganda platform to conduct personal communications. There was a time when this was done using nothing more than the United States Post Office and the telephone. So, we probably have the technology to keep in touch today while excluding Facebook.
In response to your concern with privacy controls: it’s not federated and I can only assume they’re being honest about privacy, you might consider looking at Vero. It has up-front tools to control who sees what.
Still, I would encourage people to minimize their reliance on any platform owned by someone else to maintain relationships. At someone point, something will break, will be hacked, will go out of business. Do you think Facebook will exist for 25 to 50 years from now? When it goes, all your photos and videos and conversations go with it. When someone dies, all the memories they’ve captured are gone. Hashtag: bring back photo albums.
I think you bring up a good point about college and high school classmates. I don’t personally care about this but I imagine millions of others do. IMO, these groups should maintain their own social platforms. If you want to keep in touch with your classmates from Harvard, Harvard (or a private student counsel board) should maintain a forum for you.
Right - you want to post a picture of your kid for family, classmates, friends, coworkers to see all at once. Well, that’s (supposedly) where the fediverse comes in.
The fediverse, of what I know of it, is still lacking a lot of these tools that would be useful to people. People are pushing it really hard but it is not ready for the masses.
