Really cool project, but man, way to bury the lead! I nearly walked away from the article after the paragraphs and pages and more paragraphs/pages all just telling me I already know (that existing planners suck).

Two suggestions:

1) treat your reader like an intelligent adult and assume you DON'T need to provide the entire history of planners and why they suck since the dawn of time ... just spend a few paragraphs outlining the problem you are solving, like every other (good) technical article ever

2) if you are going to write a million words before getting to the part everyone actually wants to read, at least provide a link at the top and a warning "I am writing pages and pages on the history of planners that likely no one but me cares about: you can skip them here".
