A client wishes to implement a Q&A section where users can ask questions about certain topics that will be answered by experts of that niche and then be published on his site.
Each answered and published question will have its own url, like: "example.com/what-is-the-meaning-of-x". Multiple similar questions will be combined in a single answer and the user will be informed, that an answer already exists. So "What is the meaning of X?" and "what is the true meaning of x?" and "what is the meaning of x if y" won't each get a own URL.
The idea behind this is to provide support but also help Search Rankings (for the direct URL but also the whole site).
Now my question: Would a page with a short answer (maybe like 100-200 words) in Googles eyes be considered "thin content" even if it answers the question perfectly? And what about duplicate content? For example two different questions that touch the same subject and therefore get a kinda similar answer.
