As the number of users continues to grow and the number of repeat questions continues to grow, I was thinking, while ya'll are updating the website to 2.0, maybe you could implement a new way to create forum topics which searches for what you type as your writing your forum topic.
Yahoo! Answers has a similar method where while your asking your questions, it says "Wait! Someone may have asked this question before" and shows some search results on the side.
How does this sound?
