could we use this website as a forum to develop new ideas for the economy? something sustainable and green. Something that can catch on to the whole world.

I can tell you're a "big vision" thinker, awesome! LinkedIn already has a number of groups that may meet what you're looking for. Sign-on to LinkedIn, go to "Interests, Groups", and use the "Search groups..." field at the top of the page to search for "green eco", "eco tech", and the like. Hope this helps, and keep the vision alive!

The answer to this question is that this website can already be used as a forum for new ideas. The key is that, like many tools of the information / computer age, as it were, they need to be leveraged. You'd think that everyone would know that, but trust me -- there are people who ask me questions everyday that could easily and quickly be answered by hitting the internet and doing a few smart, focused searches, or using a readily-available tool.

One thing I'd recommend is adding an occasional reference to "new ideas" or "problem solving" or "opportunities for innovation" to the topic header. Or, alternatively, if you're answering a question, add some of that sort of thing into the response. The header or question itself would be preferable, however, since those of us answering questions would be reminded to include some speculation or "vision" to the response. It would be nice to encourage that sort of thinking. And yes, there are other sources of such information, but there's no reason not to pursue it here as well. The folks who use these responses would be encouraged to think outside the box, as it were.
