I'm building an RSS tool for Pinboard

I'm building a super fast/lightweight/privacy-first RSS reader with deep Pinboard integration (my favorite bookmarking site) and automation features. The focus is on quickly scanning headlines and bookmarking URLs, rather than reading articles in the app (in fact, there won't even be a reader mode). I put together a page to explain the idea in more detail:

https://www.pinfeed.net/

This is something I've always wanted, and in addition to building it for myself, I'm considering hosting it as a SaaS. If this sounds interesting to anyone here, I would really appreciate you let me know so I can decide if this is something I should spend time on (there is an email signup for early access, if you're really interested). Thanks!
