FYI: New ideas first presented are always very confusing. Let it sink in. Note: The page is public - thus, if I may return the favor - change the confusing private to public in your sentence (or is that "knee jerk private commentary?").
PS: Let me add more context - The top-linked Textile Markup Language is a documentation website. Textile markup/down is history and FAILED - thus - the next step is what can we learn from the fail - what are the good, bad and ugly parts? what was missing and so on. Now how do you "fix" textile (or markdown)?
For more context let me add / point out the side-by-side samples (texti vs markdown vs latex vs wikipedia markup), see https://github.com/texti/texti.github.io/tree/master/samples using the Wikipedia article on markup as an real-world sample.
