Wiki wiki what?

So, when I saw that "wikis" were next up on the list of 23 things, I inwardly sighed a little. I've heard the term thrown around quite a bit recently, and before entering this program I had never really been exposed to the idea. (Well, with the exception of knowing that "Wikipedia" existed.) Once I delved into this exercise, however, some of that anxiety dissipated. I went through "Wiki's: A Beginner's Look", and "What is a Wiki?" to familiarize myself, and realized that they can be a potentially very powerful tool for anyone, in particular librarians. They seem simple enough, and with options related to how they are hosted (from your own server or a "Wiki-farm"), it appears that virtually anyone who would want to create a wiki, could in fact do so. I loved the city of Rochester example, where a very thorough wiki has been created regarding all things Rochester. It would be wonderful to move to a new place, or plan on attending a large event (i.e. an ALA conference in a personally unknown city), and then finding that these incredibly resources exist. I have to admit, I'm not entirely fond of the fact that information can be deleted and changed by users other than the original author, though I realize that wiki settings can be changed and adapted to the situation (i.e. Wikipedia versus a group project for a class). Ultimately, I believe that Wiki's are an interesting tool for librarians to become familiar with.
