HST - Why should you care?

A little while ago I came across an awesome video explaining some of the misconceptions about the HST and what it means. It is definitely worth taking a look at.

 I will admit that even though I thought I understood the concept fully, some of the finer points completely eluded me until I watched this explanation. This hearkens back to my previous post about misinformation and how important it is to concentrate on educating through facts.
