Problem is, my family is all in. FB, IPhones, Alexa and so on.You can do all this for free over at Proboards and not be involved in Facebook at all, and if you want to do it without advertisements you can have your own private family site for 6 bucks a month.
That gets you 60k Pageviews, which is plenty unless you have an enormous family.
I don't have any financial interest in Proboards; but I have maintained a few different forum sites there, the service has been reasonable and the cost has been exceptionally low.
In some ways it will seem very basic compared to Facebook but on the other hand they're not tracking your movements, and you have a fairly free hand with the site architecture.
If I want to communicate with them I am locked into FB. Non techy people navigate to the easiest to use technologies, which is why FB, Instagram, Twitter and the like are thriving. People choose to ignore security in favor of convienience. I keep saying it, but it will be our undoing.
