Why isn't everone using Lua
Lua seems to be an amazing embedded scripting language, so why aren't more people using it? I suspect the reasons are more social rather than technological.
I am wondering to myself why the Lua programming language is not more popular as a scripting language. It has an excellent and stable implementation, great performance, and great documentation. Sure, it has some popularity within game development circles, but not many people are using it outside of those circles.
