This won’t solve all of our redundancy issues but it could solve some.
Every time someone posts a question or asks for a solution to a problem what always seems to happen is 10+ people posting the exact same thing, even after the thread’s creator says “thanks that fixed it”.
Solution: What if we could modify threads so that there is a specific sub-type, some sort of “Ask a New Question” thread creation option. In this thread the creator will have an option, on each answer given, to select it as the correct solution. Once a solution is determined to be the correct it will auto-lock the thread so that it won’t be kept in priority due to people repetitively adding redundant or irrelevant responses. The thread will die as it should after the problem is solved.
I’m sure this will require some coding but the end result will be nice, I think.
