Not sure why you'd be shocked, it's a solid language for enterprise services like Apple offers, and their other languages - C/C++, Objective-C, Swift - aren't very kind for web services.
Great use case for Go though, especially its concurrency features for web crawlers. I reckon Scala could work too, although it's a lot more complicated / clever.
