This reminds me of one of my favorite Mac apps ever, Feeder:

Literally, the only app I miss after leaving the Apple ecosystem.

The question I always have is how to keep a permanent archive of entries for long-running publication histories. You don't want the feed to grow without bounds, so paging (by time period or sliding windows of X entries) seems useful. Atom feeds have RFC 5005 links. I don't recall such for RSS 2.0, but it wouldn't be that hard to extend, I guess.

clever. i personally don't see the appeal of limiting my blog to rss readers only - i like having a web link that can be shared. this would almost be better as a sort of covert blog, like maybe a smallnet adjacent thing -- no potential to be shared on hackernews is a pro for many ppl.

I love RSS as a way to subscribe to news feeds. But I want my RSS to do just that: when I click on the link, I want it to open the original website.

I have tried the "reader" part of many RSS apps, and to me it always sucks. If the original website is unreadable, I just don't subscribe to it. It if is nicely done, then the RSS reader usually makes it worse.

I once implemented my blog as pure RSS, but also a website that could render arbitrary RSS feeds as a normal looking blog. (Passing the RSS feed via query parameter).

The nice part was that the bit that was mine was just a single static file.

The awkward part was the URLs looked crappy.

It used to be possible to make bare RSS very readable with XSLT.

Barry! Funny seeing you here. Slick design on this

Too few people use RSS to limit your audience to this.

Have a website.
