I have not used Lua for web apps, but I do know that the Kepler project is quite active these days. They're developing a whole suite of tools for a Lua web stack. www.keplerproject.org
Personally I love Lua as a language. It has just the right blend of functional, imperative, and OO concepts to let me dabble in different styles as I see fit. It's an elegant language which also has a great community.
Lua is what I turn to when I want to prototype an idea or just scratch out a rough draft of some calculations. I have yet to write any in-the-large software in it, but I suspect that it would scale nicely as well.

Anyway, have fun with Lua. I know I am!
