The problem with any new initiative in this space is that it enters a field that is more than well populated. It doesn't matter if existing solutions are less than perfect.<p>Its like walking into a historic European city that has architecture going back millennia and arguing for a great new building design. Greenfield space is scarce and people will not just demolish old structures to try something new. They need to sense overwhelming advantage.<p>The analogy gives some hints as to what needs to happen for a new approach to take hold. In building construction, <i>massively</i> better use of space was one example: For better or worse, use of steel and reinforced concrete opened the vertical dimension and the rest is history.<p>Is there such an unexplored dimension that could entice people into yet another document format to "improve" on ascii, restructuredText, wikitext, markdown, tex/latex, asciidoc, html etc. etc.?<p>The stock answer is some sort of semantic hypertext infrastructure. The original vision is still unfulfilled. If we assume that the walled gardens of today are just a bad nightmare that will pass away, in a re-decentralized web one would need modern, user-friendly and empowering document writing infrastructure.<p>But there might be other dimensions that would elevate document writing and sharing to new heights. The beauty of innovation is that it is not bound by conventional rules and pre-existing wisdom.
