> Software is fundamentally broken. It's limited, never quite works the way we want it to, but it can't be changed, can't be combined and can't be trusted.

In general, this level of hyperbole puts me off. Besides anything else, this sentence is outright false, since much software can be changed, combined, and trusted. I know it's a manifesto, but still, this kind of rhetoric is unlikely to persuade people who don't already agree with you.

The issues you are discussing in this manifesto are not new, and many people have attempted to create tools to tackle those things before. Perhaps try to clarify why you think those tools fall short, in order to persuade people that zells is useful.
