@humanetech Thank you! Part of my brain keeps whispering: we should be able to do that (push announcements) in a federated fashion - from Mastodon to Lemmy at least :) Copying same thing to many different places is time consuming.
The #Murmurations idea is a bit different.It allows anyone to publish any data at their location of choice, and conforming to a specific profile. This information then federates to different instances where people can subscribe to it based on profile metadata they are interested in.
Interested in ClimateChange, SolarPunk, OpenScience? Subscribe and the data (which can be anything) starts flowing to you from all across the #Fediverse
