I've recently been sparked by the Google Go language. It's a server language that has a lot of the power of C++ but super easy to use. You can even use it to make Desktop applications if you use the Go-GTK GUI library. Plus it's easily cross platform.
If you remember the past chat box games, the servers were made in Node.js and the client was made in Javascript. In my SpaceCraft game(which I'm still secretly working on), I switched Javascript to Dart. Google Dart is much easier to make webpage programs in. And now I will be using Google Go for the server side for better ease of use, better error handling, and tons better performance.
