What's A Wiki?
My friend Billy asked me what a Wiki was yesterday. We talked about it a bit, but here I am to talk about it a bit more. A Wiki is an online repository of information that can be edited by just about anyone.
The most notable example is Wikipedia, a huge repository of all the information you'd ever need. Whenever I want to look up a technical term or just find general information on a topic, I go to Wikipedia for a good overview. Of course, not everything's in there, but that's mostly because somebody hasn't gotten around to writing on it. All this information is free to use, so if you have an area of expertise, why not join in and contribute to an article?
Another Wiki I'm very familiar with is the Homestar Runner Wiki. This has everything you'd ever need to know about the inside jokes on that Strong Bad email you just didn't get. Plus, most of them are there within hours of it getting posted on HomestarRunner.com. And, all these people did the work in finding those little hidden easter eggs, so you just read where they are and then go back and watch 'em.
The article that spawned an idea of a post was the following. Wired interviewed those who have made their hobby the updating of the Wikipedia. For them, the Wiki truly has become a way of life.
