I don't have a good link at my fingertips, but IMHO the killer features of Go are: - super-fast compilation, so much so that you can write Go "scripts" that are compiled and run from the #! line every time you call them, faster than it takes the Python interpreter to start; - static binaries: this eliminates an entire class of problems, such as DLL hell and OS version dependencies; - great concurrency model, easy, powerful, and safe, based on CSP; - implicit interface implementation, which makes it easy to integrate different libraries (I'm not sure what the academic name is for this feature, but it's taken straight from Common LISP, Haskell, etc.) Highly recommended. Easy to learn and very comprehensive standard library.
