I’ve stopped using FB regularly, because I don’t like their feed algorithm. I don’t like the ads or the content, and I had curated it by joining local groups and BOFS. The only thing that brings me back now is the _possibility_ of a friends update.
That said, the _frequency_ of updates from friends and family will be vastly different for different people. The feed (if it speaks to you) works to regularize or smooth the frequency. I see FB’s problem and I don’t envy them. The vitality of the platform becomes precarious, and can be supplanted by some other platform with better engagement (ie TickTock).
I’m not a designer or researcher of Social Media, but I’m an emigre of sorts and not many people have that experience. The only platform all of my friends and family use are group private messages using our phones, and the most engaging chats we have are few and far between.
