Two things I wasn't aware of:

a. subscribe to a subreddit by appending .rss, eg https://www.reddit.com/r/news.rss

b. subscribe to a Github's repo commits by appending /commits.atom, eg https://github.com/github/dmca/commits.atom

Thank you for the extensive list, I formatted it for you [1].

Next time, use double new-lines to separate each line.
