If you have ever wondered what a Wiki is, or how it works and what difference it would make to your life, wonder no more.

I have used this to explain the concept of a Wiki to people and it's amazing to see the penny drop, I can lietrally see a light go on in peoples heads after seeing this video.

Commoncraft provide several other videos just like this one which explain geeky and convoluted concepts like social media the same way, this is one to bookmark and revisit on a regular basis.
