I’m on bluesky. It got most of the twitter people I followed for humor. The protocol supposedly allows (will allow?) other servers, but for now I think it’s mostly the one. I prefer mastodon governance/structure, but bluesky has a bunch of people I want to read.
How widespread was this? I grew up in the 80s/90s and pre GPS we just had a map in the car. I’ve never heard of such a hotline until seeing this post.
