Over the weekend, I created https://robot.villas using @fedify 2.0. Not knowing how activitypub worked made this a lot harder than I expected, but did get there in the end.
Each bot mirrors an RSS feed. @nyt_travel as an example. You can add your RSS feed for funzies at https://github.com/icco/robot.villas/blob/main/feeds.yml
Let me know if you run into any issues with my new little bot farm of news.
