It is very easy to open a blog in Quora. It is not just a platform that provides free blogging option to us. It is one of the biggest question-answer problem-solving platforms and for sure it is better than yahoo answers. In Quora you can write an answer on a question in a similar way you write a blog in Blogger or WordPress platforms. That mean you can add links, images and videos in your answer that gives the platform a blogging like feeling where many people give their answers on a similar question. It not only gives the seekers a clear concept but also you get extra knowledge on the topic from answers given by others.
The reason why Quora is so popular because it helps bloggers/businesses/service providers to get good traffic to their blog/website. It also helps people to make some money for recommending products/services from here without a website (called affiliate marketing). Besides the answers get huge views that again helps the bloggers/businesses/service providers. Because all you need is just the relevant traffic to profit from whatever you are providing.
