Friendica has just been updated to version 2019.03
If you haven't tried Friendica lately, this might be a good time to take a look.
Some places to sign up:
It's the Fediverse's Facebook alternative, with a similar interface and features (photo galleries, events, groups etc).
You can follow people on ActivityPub (Mastodon etc.) and RSS feeds too.
You can also use it through the the Fedilab app (@tom79).
