https://github.com/alin23/spfy is the core of that idea. If you want I can help you or your friend set it up. Or I can let you know when the finished website is ready.
Personally, I am thinking about developing an online service, which will be offerring general-purpose providing distribution of content to Kindle or other ebook-readers. Initially, I thought about creating only a app which will extract a article tag from website and create ebook from it (pandoc) or exactly a Pocket-to-Kindle. But when I was thinking more about it more ideas had come to my mind, HN-frontpage scrapper, simple notebook/orgmode adapted to Kindle Experimental Browser, markdown-files-to-ebook, arxiv-to-ebook converter, some kind of IFFTT pipeline (stream X from Y and save it as a ebook) and even trying to implement most of features known from Calibre application... If I could somehow help you as a developer or you are interested in bootstrapping some online service together I really would like to receive an e-mail from you. My e-mail address: (put my HN nickname here) at gmail.com
The number of times Pocket just either redirects to the original article, or drops salient bits of text (in particular, unordered list items) is really annoying.
Personally I use Instapaper more for reading because of all the premium features being free and keep Pocket in sync using IFTTT for their good recommendations.
I can make you an (unofficial, free) beta tester if you want. I'll have most of the basic functionality by the end of January. If you're interested let me know here: [email protected]
I've started working on a similar service but didn't ship. I'd love to chat (email in profile).
I am now working on a bunch of ideas that I hope will help some people around here:
1. A Pocket-to-Kindle service that syncs (almost) instantly to your Kindle whatever article you save, formats it like a professionally edited book, cleans up ads and takes advantage of the new typesetting engine inside the new Kindle firmware.
2. A Spotify music discovery website. I'm trying to make a two-click-playlist-generator by using Spotify APIs to look at the top artists/genres of a user and create playlists on the fly with tracks that the user could like.
I use Spotify daily and found myself overwhelmed by how much music there is available. Because of that, I'm mostly listening to my saved songs, Discover Weekly/Release Radar and trying out playlists that usually have the same too popular songs.
3. An adaptive brightness/contrast app for external monitors. Adjusting brightness using the monitor's controls is always annoying to do.
4. A morning alarm that starts playing an algorithmically generated Spotify playlist each time, with fade-up volume, external speaker support, adaptive algorithm based on likes/dislikes and self-updating alarm times based on day moments (twilight, sunrise, golden hour, dusk etc.)
5. A detector for processes that eat up all your CPU and battery. I started writing this in Rust so I can make it cross-platform and learn the language at a lower level.
