Introduction – This Is My First Reblog I have never reblogged someone else’s work. However, when someone writes a treatise on a topic like this, I have to capture the information because I know I will need it in the future. This is a Master’s thesis delivered in the form of a blog post and…
Introduction I have determined that I will not become a video blogger (I feel like a big dork on camera!). However, I awoke today with a thought that must be completed. I feel compelled to continue this story by doing what the great Paul Harvey used to do. He would say something to the effect…
