I like the minimalist design. I built a similar daily feed for myself, using GitHub Actions to trigger a daily sync, FeedLand.com for managing subscriptions, and GitHub Pages for publishing. Artemis is much more user friendly.
This project actually started off as a GitHub Action to trigger a daily sync, with a Python script that polled pages and saved the results. A static site generator then built the site using the data from the polling process.
