The quality of the answer you'll get here will be totally random. You stand as much of a chance as getting a good answer as a bad one, an unrelated comment, a silly response or even no reply.
Is this a trusted platform? I'd have to say no, it isn't. And I disagree with TimeTraveler2's answer that you can just recognize the quality of the answer from reading it. That depends a lot on the person doing the interpretation, and a person with no knowledge of the subject (often the person asking) stands a good chance of not being able to tell an accurate answer from an inaccurate one. You see this a lot with questions about HubPages itself. Both right and wrong information can be delivered with just as much of a helpful attitude.
