I build my own rss feed for HN, because i want only see posts which reach >500 Points in a week [1].
So i did for a few other websites: Reddit r/programming (at least 500 points / week)[2] Producthunt (at least 300 / week)[3]
What I'm searching, is a rss feed where i get notified when a book author release a new Book. Unfortunately i didn't found one.
