It’s taken a few tries to get this working but from now on I believe all of the Adventures with Notenik blog posts (starting with this one!) should be automatically cross-posting to @notenik@mastodon.social.
So now, in addition to being able to keep up with the blog by subscribing to one of its web feeds, you can now follow @notenik@mastodon.social to see the daily posts.
Since Mastodon is a micro-blogging service, the full content of each post will not appear there, but only the title and the teaser, with a link back to the full post on Notenik.app.
I’m using IFTTT to do the cross-posting, following the approach outlined here. The RSS feed generated by Notenik is providing the data to IFTTT.
