Interesting comparison. I have never used Node for anything bigger than small personal stuff, because non-blocking code was never a requirement. I still dont see the value in it in scenarios like in the blog post, as all he is doing is a bunch of functions and once all of them are done, send something back to the client.

How does the client or the dev benefit from the non-blocking approach here? At the end of the day he is describing a sequence of actions the depend on each other. Why not block then?

I really dont want to sound arrogant, but I am just curious what the benefits are that I dont know of.
