I've set up a Mastodon instance for OSM (english speaking)!
Mastodon is an open source, federated micro-blogging system, with more than a million users. Basically open source twitter, spread across many servers. This is a new instance/server focused on OpenStreetMap (there's already fr.osm.social for francophone OSMers). Like email, this server ("instance") talks to other servers, so anyone on the "fediverse" can follow and interact with anyone on this server & vice versa. The "local timeline" will only show toots (= tweets) from everyone on the server, so will be full of OSM related stuff.
Let's ditch twitter for something open, and under our control! No adverts, no analytics, no "algorithmic" promoted tweets. 500 characters! Let's use mapstodon instead!
I'm mirroring some twitter accounts to it. I can turn them over the appropriate people, or continue to auto post from twitter. I'll create more mirror accounts later.
