I like your thinking of non-binge learning, and think you could really use that as a differentiator, in your marketing.
Your site looks great, and I really like the way you approach it, or describe it here, but that isn't coming through in your branding. Think Salesforce's "no software", they showed who the enemy was, and put them squarely against it, and if you really look at it, they were selling a CRM, not selling "no software", you're even closer to your product.
If you haven't yet, you may want to check out the book Play Bigger and category creation.
Just a thought, best of luck to you.
