My husband and sons had smug smiles on their faces and if any one of them had said, "I told you so." I would have smacked them. Their constant nagging about other people copying content was one of the reasons why I did not continue the tutorial. Their main concern was the amount of time and effort I was putting into it.
I never worried about copyrights before because thus far I've always found people stumbling on interesting blogs referring readers or directing them to the said blog.
Simply speaking, I never felt the need.
Now it looks like I have to water mark my tutorials and look into copy rights.
