Many people uses instructables.com to post their projects and win prizes. I think most boring thing(and reason most people give up) is documentation part of their project which most of the time they have to do themselves. But collaborizm provides effective way to document their project in project discussion’s “Milestone”(Document the project on-the-go & do with team).
Many users on instructables will be eager to join collaborizm if it provides more options on documentation. My suggestion would be make a “Generate PDF” button that would create PDF of milestones submitted on project discussion step by step that can help instructables user for their documentation.
