Ask HN: Open-ended-questions.org — like StackExchange, but for open questions

I'm thinking about building StackExchange.com for open-ended questions. Do you think it's a good idea? I have two questions:

But first:

1. There would be subdomains that corresponded to StackExchange subdomains, e.g.: programmers.open-ended-questions.org and writers.open-ended-questions.org. So if you wanted to ask an open-ended question, or start a discussion, you could visit *.open-ended-questions.org instead.

2. I've mostly built a hopefully better discussion system already, as part of a failed one-person startup, see http://www.debiki.com/-84472

Now, the questions:

1. Do you think open-ended-questions.org is a good idea? Would you use it sometimes, or perhaps people would use ... Reddit? instead?

2. Would anyone like to help out in some manner somehow? :-) For example, helping promoting the site(s), or advising about how it should be promoted? And/or suggesting features and things to add and amend.
