We see discussions, in other forums - between a blog owner and an expert, discussing the necessity for unique content. When advised that his blog is a problem because it is simply copy and pasted material, the response from some blog owners focuses on the term "copy and paste". I type everything by hand, word by word! I do not copy, then paste! But hand typed or not, the text can be easily Googled, and found in larger and better written websites. Neither AdSense, Blogger, or Google Search care whether you use the keyboard or the mouse, to add content into post editor. You can type an article by hand - or you can highlight, then select "Copy" from the right click context menu, and finally select "Paste" from the right click context menu - and get the same result.
