Here’s a rather long list of RSS feeds accumulated over the years. It has been purged on several occasions, depending on my mood and succesive jobs (e.g., rstats and stats stuff has been severely impacted in the past 6 years). It targets Newsboat, so all you have to do is put this file in your $HOME/.config/newsboat directory. Tags are not always very accurate, as the original posters may have changed their posts over time.
