> Why? Why should someone provide an email address? You get access to the courses for the “price” of your email address; the author sends you updates about the course you signed up for and mentions their paid courses as an aside. It's a common pattern in the developer education market and has long been used by Wes Bos and others: https://cssgrid.io/ https://cssgrid.io/ I signed up for Gophercises (same author as Algorithms with Go), which also asks for an email address: https://gophercises.com/ https://gophercises.com/ I've received at least one update email about Gophercises with a short note that the author also has paid courses available. I don't mind the upsell attempt at all; it's entirely reasonable given the value I got from the free course.
