Some sites allow users to view its content without having to register or login. This can be a good idea because it allows users to decide whether or not they want to be apart of a certain website, blog or forum based on the content that they can see. But do you think that it would be better to force users to register or login to view the content that you post? That way you can collect statistics and data on who reads your content. Do you allow guests to view and read your content?
