I think its cool that more people are building what I call "calm tech". More technology should try to serve a purpose quickly and then get out of the way instead of trying to artificially stay on your screen as long as possible.
nice! yeah, i agree. calm tech is a nice way to put it. the current big platforms are highly tuned to keep people engaged and enraged to the max, rss is kind antithesis of that. that's probably why big companies try to bury and hide it. youtube and reddit still give pretty good rss support though, which is nice.
Incidentally, I built my own calm RSS reader some time ago that has many similar ideas to yours: https://github.com/lukasknuth/briefly
