I don't quite understand. You are describing the Stack Exchange format. It was designed, [from the very beginning][1], as a system that incorporates features of wikis, forums, Digg/Reddit and blogs:

If you find wrong information, well these sites are designed to act as wikis and allow collaborative editing. So edit! Fix the errors!

As for finding "the best direct and easiest solution(s)", well that's what upvotes, downvotes, and accepts are for. 

So, if you find wrong answers: downvote. If you can fix them: edit them. If you find good answers: upvote. If the right answer is missing because everything is out of date: post a new answer with the up to date solution. If someone gives you the right solution to your question: accept. 

In other words, you already have all the tools to do what you describe, just use them.
