Ask HN: Share your best OPML/RSS Feeds

Even though Firefox v64 will stop supporting RSS/Atom feeds natively [see https://news.ycombinator.com/item?id=18202028 for a discussion on that news], I just found how convenient and efficient RSS can be. Before it gets harder to find feeds, I'm hoping everyone can share their OPML exports from their favorite reader, or share their favorite RSS feeds.

Aside from the Hacker News RSS Feed [https://news.ycombinator.com/rss] and adding my favorite subreddits [https://www.reddit.com/r/python.rss], I don't have too many yet.
