I meant to post this a few days ago, but since we seem to be having an exodus, here's a quick guide.
If you want an easy way to find where people are going, use the Facebook search function - but that's not all you have to do. Once you have the search term in, click on "Posts" so you're just looking at posts, then "Your Friends" and, if there are too many, narrow it down by year.
If you get a hit, remember to check the comments, because some of your mutuals may reply in comments with where they are moving to.

Blue Sky is like Twitter. All posts are public and the focus is on engagement and sharing. There's better moderation than Twitter though.
To find which friends have moved to Blue Sky, search on:
- bsky.social (the "right" way to share a profile link
- bsky.app (the common way, for people who copy/paste URLs)
- bsky (the abbreviation, may not be needed if you do the other two, but I don't fully trust FB's search function, so here you go)
These ones's aren't great, as they catch more than just people posting moving notices, but in case you want to do a deeper dive, here you go:

Reddit is like an old school BBS or Facebook groups, with different channels for different topics. Some groups are good, some are really, deeply, unpleasant. Feel free to drop a group the moment you get uncomfortable.
To find which friends have moved to Reddit, search on:
- reddit.com/r/ (this finds channels/groups)
- reddit.com/u/ (this finds profiles/people)
I don't know of any other searches that work. Unfortunately, this one is messy.

Dreamwidth is a LiveJournal replacement, best for long-form content and discussions. It works off of "circles", but basically, all communication occurs on the equivalent of Facebook pages and groups. Sharing images/media can be a challenge if you're not used to embedding images in an HTML-like form.
Dreamwidth is easy. Just search on "dreamwidth".
When people say "I'm beaksandbaubles on dreamwidth", that means that you need to go https://beaksandbaubles.dreamwidth.org/ . Once there, click "add to your circle" to follow them.
Remember to check comments on your friends' posts on Dreamwidth, as you can find more friends there.
You can also search on "dw", but know that you may match a lot of Doctor Who posts as well.

Discord is like a modern spin on IRC or WhatsApp groups. It works off of "servers" which contain "channels", so you have to join a server and then see what channels on that server you care about. It's kinda messy, but it's much more "in the moment" than other platforms.
Search on "discord". And then read about which servers and channels they're suggesting you join. If they don't mention specific servers, you'll need to ask them for more specifics.

Mastodon/Fediverse is complicated and can vary based on which server you're using. It's generally for short-form content like Twitter, but aims at growing community.
Search on:
- mastodon
- mastadon (because people misspell it a lot)
- fediverse
If people don't mention their specific server, you'll need to ask.
