Earlier quoted context omitted.
As somebody who uses Node only at the periphery of my role (for things like the Zombie browser, and SASS parsing) the massive instability has put me off from relying on it for anything core. Documentation is quickly out of date, libraries seem to have incompatibilities which only become obvious when they don't work, there's no 'recommended' approach for even basic tasks. I won't pretend I'm speaking for everyone, as…
Geez, that's a bit harsh, don't you think? I've used node on several high-volume production apps, and I haven't seen any instability. And, if the documentation is poor, then it's only poor forsomuch as one unwilling to delve into the code. Node has its place, and it's not for everything, but for quickly whipping together sturdy, flexible web APIs, it's great.
Not sure if this is what you meant, but I read the ancestor comment not as being about "will the process crash randomly?" but "will an upgrade break something in my app?"
It's just that I've seen whole comment threads go by with people tripping over this misunderstanding without ever acknowledging it.
