Why Lua? I have been running Node.js and Lua at fairly large scale on EC2 recently. I like the V8/Lua/Luajit platforms just fine. Each has some nice strengths. With Lua, I see significantly less memory use, and moderately increased performance. As long as RAM is the expensive bottleneck for hosted servers, it looks like I will be able to get better performance (in operations per dollar) by using a smaller runtime. Why not client-side rendering? Accessibility? Cross-platform uniformity? (better answer from 'capnrefsmmat: render once, then cache massively)
