We're currently working on rewriting /learn to not require any login while still retaining the gamification element (in offline storage). Meaning that you get the best of both worlds.

Just to explain the reason there is a login at all, this is mostly for historical reasons. The original learnnextjs.com built by Arunoda was based on another project he created for teaching Meteor.

Anyway as said we're rewriting /learn, using MDX (http://github.com/mdx-js/mdx) for content and the quizzes will store the result in your browser.
