HTML HREF Target - Why didn't I know that?

I've been coding HTML for over 12 years and today reminded me that it's never too late to learn something new. I don't know why I didn't know this but today I watched someone code an HREF adding a Target="_blank" to the tag in order to make the link pop up in a new window. It was on a SharePoint site, so I thought maybe it was a Microsoft-specific thing. No, said the person coding it. I was amazed. In the past I think I always used javascript to pop up new windows, but probably never again. Target="_blank" is my new friend. I even used it on this post!
