Quora

Quora is an English-language question-and-answer community covering everything from technical problems to career and life questions, with answers written by individuals rather than assembled by an editor.

Answer quality varies enormously: some come from genuine practitioners and are better than any article on the topic, others are marketing in disguise. The upvote ordering helps but does not filter reliably, so checking who wrote an answer matters as much as reading it.

For businesses it can be a slow but durable traffic source — a well-written answer to a question people keep searching can send visitors for years — provided the answer genuinely helps rather than pitching.
