Talk to the people who wrote the first book on Meteor.js. I know they pulled in over $500k. That's probably a unique case because in the beginning the documentation was so bad, but especially in new and esoteric programming languages/methods $50 is no big deal, and there are lots of willing buyers. I'd bet the HaskellBook authors pulled in 100k+ too. |
