The only social network idea I would take seriously (here my own idea ... feel free to copy) is:

1. You use your existing email.

2. You create a desktop app that reads your email, and if the email is "social" you import it into your locally stored feed.

3. For those who want it online everywhere, some end-to-end encrypted web thing to act as the desktop client.

Voila, you have a way to keep in contact with friends, and keep photos / timelines of everyone.
