Make money from blogs - What does fair use actually mean ?

Fair use is one of the most debated terms in copyright / content issues. At a very non-legal level, fair use means that a person is allowed to refer to a section of somebody else's content as long as it is meant for purposes of reviews or as part of creating new content. There are limitations in this though, since even for fair use, you cannot copy the main idea or use something that is published very minimally, and other restrictions.

So, let’s start with a fairly common sense definition (and since I am not a lawyer, you should take anything said in this article as common sense, not legal advice). Fair use is meant for the case when somebody wants to use your work to do a review, praise or criticize. That is allowed and perfectly legal, but what is not allowed is to copy the main few concepts from your content and use that under the guise of fair use. When somebody uses a small section of your content, they are actually using your content to create new content, not creating a copy of your content.
