While Q&A sites are certainly a good place to find answers to one's problems, I think it would be better to collect solutions. During my daily work I quite often solve a specific problem. Wouldn't it be nice if I could store the solution somewhere so that others can find it (including myself if I have the same problem later and forget how I solved it)? Kind of a Code Snippet Repository.
I think the quality of the solutions would be much better this way. You could also formulate questions and attach them to the solution (= answer), so it would look and behave like a Q&A site. The process of posting a solution would have to be very easy, of course. Nobody wants to spend too much time after solving a problem. I imagine that there has to be a tight integration with the OS or IDE, maybe directly allow posting of marked code with a shortcut.
What do you think?
