You can always ask for clarifications. As with Google Answers, the results are public. That means it pays to search the site for previous similar questions. It also means that your answer won’t be confidential.
If you want advice, go to the free and free-wheeling Yahoo Answers. If you want help on a particular question that the exact right person can answer quickly, I think Ask Metafilter is by far the best guru (and it is free for members). But if what you need is some real research and serious sleuthing, the kind of answer that is not just sitting in someone’s head, your best bet may be Uclue.
