Thanks to an inquiry posed by @wendy yesterday, I discovered two amazing projects to map community events from aroubd the #fediverse on an @openstreetmap base.
«𝖛𝖔𝔦𝔡 balotta» by @grafton9 shows venues listed on https://balotta.org, an Italian @gancio server.
🗺️ https://autistici.org/void/balotta
«vous revoir» by @simon shows events listed across both @mobilizon and #Gancio servers.
🗺️ https://www.vousrevoir.be
