There's nothing in the main ecosystem for getting news content on the device (besides manually sending individual articles to the rM via the chrome extension).

I'm working on a project that pulls from RSS/Twitter/Reddit, formats all your subscriptions into a single pdf, and syncs to Google Drive (which the rM can sync with). It's working great for me so far but is the closest to "automatic" I think you can achieve with the device right now.

Also have a remarkable. While hacking it is reasonably easy, you would need to do a bit of it to make this work smoothly I think.
