Personally I think that a lot of the ideas and gripes (especially the initial thoughts John published that sparked the whole thing) are quite valid. There is definitely room for improvement in many ways. And the fact this is an open source product is great. But at the moment it's all too young and too early to make any proper judgements.

Plus, despite what people (seem to) say, it doesn't have a simple setup at all. Most hosts don't support Node.js - whereas almost all hosts support PHP. I don't care what tech software is written in - but for mass adoption you have to use what the masses have available.

Of course in 5 years time the adoption of node.js could be much higher - but then WordPress (and PHP) will have changed a lot in 5 years as well.

Either way - I agree that competition is good and I'm sure both apps will learn from each other.
