Wiki, wiki, wiki...

What is a wiki? Is it a character from Star Wars? Is it from Fraggle Rock? Is it a dance? Where does such an odd name come from? Why do I need one? Is it a new word in the dictionary? You know like EVOO. Of all people that use the internet, I use it for mainly silly stuff like facebook, email and an occasional few other sites, why do I need this. I am sure there is some reason. Why is there a thing called tag or bookmark. Is it a game or a place holder in my favorite book? My mind is really trying to understand this, but am having some trouble. Maybe Shannon knows the answer. She looks like a Wiki person. Maybe not. Maybe I am not meant for a Wiki. Maybe a Wiki is not meant for me. Either way I will try my hardest to figure it out. We shall see what the world of Wiki holds for me. I am thinking not much, but there is little hope.
