RSS Parrot, a Fediverse service that lets you turn Mastodon into your feed reader. The Parrot follows the RSS or Atom feeds of a large number of websites, and sends out a toot whenever a new post is published on one of them.
Every feed has a dedicated account. If you follow that account, you'll receive a toot in your timeline whenever a new post shows up in the feed.
Let's call the things we write and publish on social networks posts. That term has the longest history, it's simple, one syllable, and isn't tied…
Let's POSSE to Mastodon with a Feed and a GitHub Action
After building a Node script for my own POSSE needs, I thought it would be good if other people could also use it. I knew not many people would be able to use the script as-is, so I built a GitHub Action that is much simpler to use, without losing any feature, even gaining some!
