Hiya! I'm the creator of the blog, really appreciate the feedback, it's actually made my day (and it's only morning!).
I'll look into adding an rss as soon as I have some time. Looks like it should be pretty straightforward with Astro: https://docs.astro.build/en/guides/rss/
Will post a reply when I have it on. Send me a message on LinkedIn (see profile) if you want me to DM you for an update.
