I wrote "Learn Java the Hard Way" after Zed asked/encouraged me to. I think if someone got together 52 exercises, he'd tell them to go for it.

No pun intended, honestly.

Just needs someone to step up and one day it might be listed here: http://learncodethehardway.org

Zed's said on twitter that he's been messing with Go. It might be somewhere on his work queue to write about it.
