For better or worst, Fb has become the de facto place for cruising sailors to share information about different regions of the world. Tips, alerts, advice, questions, etc. I sail the world and there is no other place for groups quite as good for finding the information we need. There’s a niche group for every area around the world full of people sharing advice and answering questions. The good groups have great moderation and quality content.

They can move to Discord, Whatsapp (huh!), Signal, Reddit or some sailor forum.

If FB disappeared they could reroute.

Bigger things are disappearing and we are going to be fine*. E.g. much world trade with the US.

looking at this feels like the best case for fediverse-based socmed like mastodon or lemmy. Though maybe too complex for regular users.
