As Joe explains in this video, sharing 3rd party content can actually be the best thing for your business. 

Why share 3rd party content? Well, think about it. Do you sell to someone who likes golf? What's gonna probably make you stand out better: an article that says come buy my product, or an article that says, hey Bob, I'm thinking about you, here's our article on golf, or hey Tina, here's a really cool article about Pinot Noir because I know you love red wine? That kind of content is going to get people to discover you, and then and then absolutely, you can give your pitch!
