Donovan and Kernighan's "The Go Programming Language" is one of the best pieces of technical writing I've ever read. Buy it and read it cover to cover.
Then read the [Go Language Specification][1] cover to cover. It's dry but refreshingly not legalese.
Learning Go by Jon Bodner, particularly the newest edition, is also excellent.
An aside: are there any other Go books, particularly ones the explore more specific topics, that are recommended? I've read a few that I didn't find very impressive.
The language spec was so good I was able to make tangible contributions to an open source project just by using that and I don’t consider myself a go programmer at all.
I want to buy that book but it’s technical and I feel like there might be a second edition around the corner?
