I realize your experience on Quora depends on what your interests are, and the type of questions you ask and search for. This determines the types of people and answers you come across. So everyone has a different experience based on what you do on the site and your interests.
From the questions I've searched for, and the questions I've asked, I've come across really great people who have provided me with helpful information and insights.
There are many questions that arise that searching google doesn't help. For this I need to pose the question to people, not a search box. There are many communities on the internet I can go to pose the question and Quora is a really useful one.
I do wish Quora would change the policy to let anyone benefit from and read the answers.
