A while back I built a site that converts RSS feeds to ActivityPub actors that you can subscribe to from Mastodon and other ActivityPub-compliant social networks: https://bots.tinysubversions.com/convert/
I've now also published the source code: https://github.com/dariusk/activtypub-to-rss
@darius I’m getting “Error: Bad Request” when I try this with http://feeds.pinboard.in/text/popular/?count=15
@lars I'll take a look, thanks
@lars the issue is that it's not the RSS feed, this link is the RSS feed: https://feeds.pinboard.in/rss/popular/?count=15
(you need to replace "text" in the URL with "rss")
@darius thank you. @pinpopular works now. I must have missed the text in the URL while on mobile.
