Bridgy Publish launched four years ago with the ability to create posts, RSVPs, comments, and likes on Facebook and other silos. It’s created over 30k silo posts since then (details), 7k on Facebook specifically.
After the Cambridge Analytica scandal broke, Facebook started limiting its API in a number of ways. Notably, it disabled RSVPing yesterday, and will disable posting on August 1, which will effectively kill Bridgy Publish. More background in the docs.
I’ll send Facebook notifications to warn users that they only have a few months left. RIP Bridgy Publish for Facebook, we’ll miss you. So long, and thanks for all the fish!
