Get your loved ones off Facebook
The entire appeal behind Facebook is the huge user base.  Everyone I know is on Facebook, and so is everyone they know.  If you're going to get people to switch, you'll need both some killer feature that sets it apart from Facebook and some means to mitigate the loss of that user base - perhaps some compatibility layer where information that wouldn't reach your friends that switched with you to Platform X gets posted to your linked Facebook account.I'm ultimately envisioning a future where people could host their own Facebooks or set up an account with a family member or small business, seemlessly transfer their data between servers whenever someone wants to switch providers, built-in SSL for everything, PGP with automatic key sharing between friends, encrypted file storage, etc. - everything that tech community advocates for in an easy-to-host-yourself distro.So much good could come out of having a standardized platform for social media; you just have to be able to overcome Facebook's inertia.
