Haskell Programming (EARLY ACCESS)

There are rather few recent Haskell texts with beginners in mind, and Chris of the https://github.com/bitemyapp/learnhaskell fame is probably one of the most qualified people out there to teach the subject.
Anything that helps people get started and advance through the skillset is a huge boon to the community.
I'm flattered (thank you OP!), but I didn't intend for this to be posted to HN yet. I announced on Twitter where my followers know me and my work pretty well.
I'll talk to my coauthor about what she thinks should go into a sample PDF and see what we can get sorted.
Also, this was a direct link to the Gumroad page, there's more explanation and background here: http://haskellbook.com/
Edit: Another note regarding content. We have a lot more done than 75 pages. We have almost half of a 500-600 page book completed, but we're waiting for some last minute reviewers to finish sending feedback before releasing the next batch of material.
Edit2: Sample is up on the site now, direct link at: http://haskellbook.com/images/sample_pdf_v1.pdf
Hope the approach/style for learning Haskell appeals :)
