Agreed. It's too bad it's hard to discuss complexity issues at that level in blog posts - it tends to skew things towards overly trivial examples. I'm curious

Agreed. It's too bad it's hard to discuss complexity issues at that level in blog posts - it tends to skew things towards overly trivial examples. I'm curious how suitable node's callback-centric model is for larger codebases - it's workable for smaller stuff, but can turn into spaghetti code quickly, like CPS code or giving someone elaborate instructions in passive voice. (Of course, relatively autonomous chunks of the system can be moved into their own processes.) Off and on, I've been working on a similar event loop/async server framework in Lua, and I think Lua's coroutines make the resulting code easier to manage. (No time frame on that yet, btw.)
