I don't know if there's such a thing (maybe I should write one myself, as I plan to learn F# :) ), but a cheat sheet that is a bit higher level would be useful.
Can you go straight to this book or do you need to get a certain comfort level with f# first? I have the latest edition for F# 4 but haven't read it yet, plan to as part of my learning the language but haven't figured out order.
I certainly looked at the cheat sheets, played around a lot, read lots of online tutorials. Only once I had a basic understanding did I read Don's Expert F#, its great, but not for beginners.
That's a great idea. If you set up a github or wiki, I'd be happy to help out and fill in areas. If you want to get more people to help, market the cheat sheet as "The Right Way".
There's no better way to invite help from strangers. :)
