For those who are wondering why we changed the blog web address, it was mainly due to the fact that so many people got confused with the "d2" and the "d squared" name, so a change was needed. Why Cornerstone, is because the foundation of any structure is built on a solid base. That base starts with the Cornerstone, and the Cornerstone keeps the entire building from collapsing. Hopefully you can see the parallels... :)
