Dr. Scott McLeod sent out a Tweet last night announcing that the fourth version of Did You Know? (also referred to as Shift Happens) was going to be released today. Well I just watched it on Scott’s blog and now you can watch it too. This version was done in the same spirit as the previous versions, but has less of an education slant and more of a business slant. To learn more about the development of Did You Know? and see the previous versions, visit the Shift Happens wiki.
