Q.E.D. is an initialism of the quod erat demonstrandum, which means “that which was to be demonstrated”.
This post is a new form of demonstration. This morning I recieved a tweet. The tweet pointed me to a post on a blog. The post was posted because one of the Facebook friends of the blogger posted a link to an editorial from April about the reluctance of the publishing industry to embrace change.
Read it and ponder on the subject of Q.E.D.
