The other day I was explaining to someone what a Wiki is, though I didn’t do a very good job because it’s something that is a bit difficult to explain off the top of your head.
Well, now I can redeem myself by posting this excellent video about Wikis which simplifies and demystifies the entire subject.
this is the coolest way to explain something. Now, even my bro understand what is a wiki (and my bro is not a very smart person)
