I've had the same issues navigating their documentation. About 10 months ago I attempted to write a reddit scraper using Racket. I started out reading their "net/http-client" library and had to turn to the /r/racket subreddit to find out that the "net/url" library was what I wanted. I'd love to see some simple directory that relates development intention with a library: "Web Scraping, JSON parsing => net/url".
