Ask HN: How do you make learning fun?
This could be answered in two ways: either how do you personally make learning new things fun for yourself OR if you were designing something that teaches, how would you make it fun?
Second, to make learning fun, it has to be designed like a good computer game: the difficulty should be slightly above your ability. That way you feel challenged and not bored but not too much so you become frustrated.
I think we are still far away from truly "personalised learning" but it's gonna be a game changer.
