@Edent https://www.w3.org/TR/activitystreams-core/#extensibility shows examples of GeoJSON integration
@Edent whether or not any implementations will render / recognize it is another matter of course
@cwebber thanks - that's realy helpful.
I'm a little confused by the difference between places and locations. https://www.w3.org/TR/activitystreams-vocabulary/#dfn-location
But I'm sure I'll muddle through!
Pixelfed shows locations. I might see them if I'm looking for them.
Of course, I might also be the guy to add "location": {"type":"Place","name":"The end of the rainbow"} just to see if someone calls me out on it.
