I'm a little surprised I didn't see more people mention Go honestly. It's kind of easy as a language to pick up, and depending on what you're doing, it might have everything you need in one swoop. Of course I've not done anything too advanced with it yet. Although uAdmin seems to be a Django inspired thing from Go, I'm not sure if it will ever take off or what, but it seems interesting at least to me. The name is kind of terrible though.
