There's certainly something to be said for stability, but node continues to use abandoned versions of the V8 engine, which, increasingly, is going to be a problem.

Software does tend to remain stable if you never make any changes to it, but that's not necessarily the right path.

Oh well, if nothing else, this whole io.js thing has set fire to joyent. It's nice to see something happening at last.

I guess competition is a good thing.
