With a little more effort HN could be turned into a hierarchical todo list or project organizer. It would help me a lot in organizing my daily tasks and projects (provided I could keep a couple of pages private or share a couple pages with my team via invite). If the owner doesn't have the time he/she could either opensource the codebase or sell people a version for self hosting. btw what is it written in ?
It's written in Arc, and it's already open source. It's in the Arc distribution: <a href="http://ycombinator.com/arc/arc2.tar" rel="nofollow">http://ycombinator.com/arc/arc2.tar</a><p><i>edit</i> correction and link
