Very simple. I have a blog and I own a URL. I cross post SOME posts at Medium but you’ll notice (check the HTML) that I am very careful to use “rel=canonical” so that my Google Juice remains at hanselman.com. I’m happy to use the Medium network effort to boost my audience, but I won’t be moving my blog to a system I don’t control, be that Medium, Facebook, Blogger, or whereever. http://www.hanselman.com/blog/YourWordsAreWasted.aspx
