I've been using Quora for a few months and I have found it VERY useful. Mainly due to the quality of answers being far better than anything found in a simple Google Search. Also, the user base is very transparent. There are many influential web users on the site with plenty of good knowledge to share. The fact that you can ask a question to a user without being their friend is also helpful. With the release to the public, I fear that the quality of questions and answers will fall to something similar to that of Yahoo Answers. Let's hope not.
