because you dont fix everything with another layer of indirection. add in some more queuing (which as we know never has a problem) just to ger around 'no threads' seems stupid.
In a classic thread-based system, it's okay if a single page takes a bit longer (e.g. >1 sec) to render if it's within your user's line of expectation.
You can't do that here because you'll block all the others.
But any decent developers knows that, so he takes the advantages Node.js offers and fixes the disadvantages that come along with it. Big deal.
Is this discussion really only about the scalability tagline? Some taglines are misleading, really?
