Great question, Deena. As a writer of more than 30 years, I'm well aware of copyright issues, and any one who wishes to hold tight to intellectual property should be prepared to go after those who steal their work. And until the Internet came along, I was vigilant. (Interestingly enough, the magazines for which I wrote, were among the first of early perpetrators when it came to publishing content I had written for which they had purchased only rights to publish in the magazine.)
Since I began writing online or publishing online content that I own that has appeared elsewhere, both the focus of my business and my attitude has undergone a major change.
Any online writing that I do now is strictly in support of my business. It's PR. The purpose is to get noticed, to bring in customers. Initially, it was as a freelance writer, then as a life coach and now as the author of Celebrate Green! If people want to use what I write, as long as I am given credit and a link, I'm a happy camper.
I don't appreciate it when, for example, someone takes my coaching website and copies it exactly, which has happened to me, but I chalk it up to the cost of doing business. When it comes to the book, if we publish any of it online word for word, it will have copyright warmings all over it, but the reality is, I don't have time to chase these people down who ignore the law, nor do I have the money to pay someone else to do it. If someone brings it to my attention, I'll email and ask for the offending passage to be removed or whatever, but I can't spend time worrying about it.
I prefer to adapt the attitude of finding a way to make what appears to be a negative work for me. So far, it has.
Warmly,
Lynn
