A search engine often returns pages containing words from your question, but not necessarily a direct answer. When I wrote about Quora in 2011, I found its question-and-answer structure interesting for that reason. You could see how different people explained a subject and ask your own question.
Quora still describes itself as a place to ask questions, find answers and share knowledge. It is not a search engine guaranteed to put the right answer first. Quality depends on the question, the writers, their sources and any interests they may have.
Ask a precise question
A useful question explains the problem you are trying to solve. Instead of asking only which tool is best, say what you need it for, what constraints you face and what you have tried. Search for existing questions before posting a new one; somebody may already have explored the topic in detail.
Read more than one answer. Look for specific experience, dates, sources and an explanation of the reasoning. A confident tone is not evidence. For legal, medical or financial matters, check important claims with competent institutions or professionals. Never make a major decision on one stranger's answer alone.
Share what you know
If you answer a question, respond to what was asked. Give context, state limitations and disclose relevant interests. Quora's rules say promotion should not replace a useful answer.
For me, Quora's value is discovering perspectives and follow-up questions. It is a starting point for research and conversation, not the last step in checking facts.
