Nobody knows how the whole system works

One of the surprising (at least to me) consequences of the fall of Twitter is the rise of LinkedIn as a social media site. I saw some interesting posts I wanted to call attention to: First, Simon W…

The Astrosky Ecosystem: An independent online platform for science communication and social networking

While almost everything that astronomers study occurs in the vacuum of space, astronomy itself does not `happen in a vacuum'. Interactions between scientists, as well as outreach to members of the public, improve extensively from access to good communication tools. Social media has become a key tool for communication in astronomy, being widely used by individuals and organizations alike for networking, outreach, and more. However, traditional social media is reliant on benevolent corporations providing a free service without compromising on quality, and the recent takeover and decline of Twitter has shown how vulnerable these platforms can be. In this proceeding, we present The Astrosky Ecosystem, which is an initiative to develop open-source tools and integrations for social media, principally the Bluesky social network. We explain how our project enables the astronomy community to operate its own social media infrastructure, independent of for-profit corporations. We also discuss some of the project's technical aspects, including its use of the AT Protocol for social networking, before concluding with ideas for the future.

Note: This was originally published as a LinkedIn post on November 11, 2025. I need to make a painful confession: somehow, LinkedIn has become an important social network to me. This isn’t necessarily due to LinkedIn’s sparkling competence, of course. To the contrary, LinkedIn is the Gerald Ford of social networks: the normal one that was left standing as the Richard Nixons and the Spiro Agnews of social media imploded around them. As with Gerald Ford, with LinkedIn we know that we’re getting something a bit clumsy and boring, but (as with post-Watergate America!), we’re also getting something that isn’t totally crooked — and that’s actually a bit of a relief.
