it's simple to use when one has an understanding of networking principles.I wouldnt say it's simple to use has "PHP",where bascially as long as you can download WAMP,write echo and use FTP you're good to go.

It's definetly not simple to write webapps in nodejs,where a simple exception can take down your entire node server.

I'd even say go concurrency model is simpler and easier to use than nodejs.
