The recently launched Quora grabbed my attention as soon as I started using it. I find myself spending more and more time on this question and answers site and it seems that I am not alone.

What makes it so awesome?
1. Authority – I am still amazed with the depth of the answers on the site. Let me give you an example – a question was asked about  the causes  failure of AOL Time Warner merger. While on Facebook and Twitter such a question would be answered by many, but not the most knowledgeable, on Quora, Steve Case (AOL chief at the time) himself gave his point of view on the matter. When a person asked how did Amazon decide to enter the cloud computing market, Amazon’s CTO answered him directly. What else could you ask for? In a sense, the fact that content is edited and removed if not informative enough, makes this platform so great.
2. Content discovery – Quora is all about topics and people. You can follow a topic or person over time and continuously learn more. This is just awesome. I follow the topics I am interested in, and people I value their opinion and knowledge.
3. Ease of use – first time you use it, you already know how to find relevant questions, as well as post your own.
4. Diversity – whenever I login, I find a question about SEO techniques, followed by a philosophical question about the meaning of life. As a guy who loves to read random Wikipedia articles, this site is a great way to learn about topics in the world around us that normally we don’t stop to think about. This thread is a great example.

I love Quora – it’s a key part of my online toolbox. If you didn’t try it yet – I highly recommend you do.
