They did a very good job attracting core early contributors who wrote unique great content and then it snowballed. Reading answers posted by the top 10 contributors is just fun. All content is SEO-friendly. Much of it is authoritative and Google loves authoritative content. There is a setting to make my content appear as anonymous to search engines, but many of us associate our names with our content. Most of Quora's content is evergreen. They improved question merging recently and that resulted in a high concentration of high quality answers to popular questions. Quora's management calls them canonical questions. The ask2answer flow also improved. You can now find people who can answer your questions. That feature was previously under-developed and didn't work very well. Quora's top contributors enjoy the virtuous cycle. We write answers and people upvote them, which introduces other readers to us. Our audiences are massive. I only have about 250,000 views per month and about 5500 followers, but some other writers have several million per month and more than 20,000 followers. Quora will collapse answers that are highly upvoted but incorrect. This helps with site quality and likely pleases Google. I am one of about 800 Quora's Top Writers ( http://quora.com/Leonid-S.-Knyshov http://quora.com/Leonid-S.-Knyshov ) if you have any specific questions.
