I don’t use social media to stay connected with family. I lift up the phone, go visit, or if we need to communicate online, I have an XMPP server for the family with end to end encryption. Can share pictures, text, and can even do video calls if need be, send files, and so on.
Don’t see the need to involve any kind of social media.
It’s about 5 times longer than previous releases were maintained for, and is an experiment. If there’s a need for a longer term support branch, there will be one. It’s pointless to start maintaining an 5+ year branch with 0 users and a handful of volunteers, none of whom are paid for doing the maintenance.
So yes, in that context, 15 months is long.
