Inspired by this post, I was wondering what RSS feeds you all subscribe to and how you read them.

Here are mine:
http://feeds.reuters.com/reuters/topNews
https://www.pbs.org/newshour/feeds/rss/headlines
https://www.pbs.org/newshour/feeds/rss/world
http://feeds.nature.com/nature/rss/current

I'm just started using Newsboat, a CLI RSS reader, to read in a few feeds (Reuters was one of them :( ) and it's pretty refreshing to get a text-based newsfeed with no distraction. Though, the feeds I'm subscribed to only give me a brief blurb of the news...

Every now and then I come across a limited-run podcast that wrapped up ages ago and I want to add it to my feed. I don't want to manually click through the old episodes one by one, I want to subscribe to it as if it were being published in realtime. Are there any tools that can help me with this?

I think what I'm looking for is some sort of app that republishes an existing RSS feed with a date offset based on whatever recent date you subscribe to it. Even better would be something that lets me specify my own custom drip rate so I can binge through large catalogs at my own pace.

I've been thinking about coding something like this but I don't want to reinvent the wheel if an existing solution is already out there.
