I did a brief post on Twitter and LinkedIn about this today with a picture of my own personal site. I was then immediately pinged by individuals wanting more of an explanation as to what they were seeing. Below is what I originally posted as well as a several minute video explaining what I have. If there is additional interest, I will record/post a "Show Me How" video going in depth and build a site in real time.
From earlier: "Do you have a personal site at work for sharing information, building personal brand, centralizing the sharing of documents, blogging/vlogging/podcasting, and more? You should! Leverage the power of SharePoint Communication sites and enhance your internal presence today."
