Everyone learns different things at different phases of life. And when they do, they're excited to share. And if they have a website, they will write about it there.

Think of this way. It doesn't matter if the message/info you are sharing is already written about. A ton of people didn't know about it. So when the message is written about again by YOU, more new people will know about it. And read it. Sucks for people who know about what you are sharing. But you're not writing for them, are you?

Not to mention, even if a person already know about the topic someone wrote about, there is still new perspective and angle to it that this piece might have. So, read it for different perspectives or angles!
