I made News Minimalist — a news aggregator where all news is ranked by significance on a scale from 0 to 10. The ranking lets readers select a "significance threshold" and ignore all news below it. It's making close to $1000 MRR now with all money coming from premium subscriptions: users can personalize their feed with category/country filters, block topics and get access to news summaries. https://www.newsminimalist.com/
