I have to admit that I have not really paid much attention to Quora.com, a community where users can share information with each other. From the looks of it, it looks much like a modernized version of Yahoo's answers.com service where users can ask questions and everyone can chime in and post answers or responses.
If you stumble upon Quora links in Google's search results, the results listing of another search engine or links that point to the site from other sites, you may have noticed that Quora.com blurs the responses on the site after the first one. This is similar to how Experts Exchange handled things previously, effectively forcing users to register before they can access all of the contents the site makes available.
But, this is not true for all site referrers. Just visit this Techcrunch article and click on the "What are the most surreal places on can visit" link that brings you to Quora. When you do so you will notice that all responses are readable right away even if you did not sign in to the service.
How this can be? Easy. Quora seems to check referrers and based on that, it either displays all contents to you or only the first response.
A paragraph in the sidebar explains the reasoning behind the decision
Quora is a knowledge-sharing community that depends on everyone being able to pitch in when they know something.
So, even if you have nothing to say about the topic or do not want to, you are forced to sign up first before you can read all the answers posted on the site.
If you prefer not to, you can take advantage of the fact that Quora does referrer checks to decided whether to display all contents to a visitor or only the first response.
Let me show you how you can read all Quora.com answers without signing in first.
Reload the Quora page that you want to access without signing in and et voila, all blurred responses should now be visible in clear text.
Update: As pointed out in the comments, you can also append /?share=1 to the end of web addresses on the Quora website to display the question and all answers right away on the page.
Update 2: The Firefox add-on Quora Sneak can also be used for the purpose.
