As I was eating some Chicken Katsu Don at Aoki this evening it occurred to me that the ideal tool for brainstorming ideas and ranking them hasn't yet been invented for the web, and that both the
One thing I definitely need in an idea database: a way to link ideas easily. Links between ideas can be parent/child relationships, sibling relationships, duplicates, and requirements (this idea can't happen until these three ideas have been implemented). It basically needs to be an instant outliner, except the outline must be able to handle branches that split apart, come together, and overlap without requiring redundancy. In other words, I don't want to enter an idea twice just because it belongs equally in two parts of the outline.
In my ideal idea tool I'd also like to have a mechanism for people to assign value to the idea along a bunch of different axes. For example, how "cool" is the idea, how much money will the idea make (and how certain are you about that), how much time would it take to do this, how much of this idea could be leveraged off of other ideas, is it a strategic idea, is it something that just needs to happen no matter what, etc.
I can almost see the tool that would do this, making it easy to group ideas, reference ideas within ideas, attribute ideas to idea-makers, attach ideas to projects later on, comment and vote on ideas, report on an idea's actual metrics after it's implemented, etc. If it leveraged everything we know about creating
