Wikipedia

I configured a wiki recently, and wanted a way to categorize the articles in a hierarchical structure and display it in a visual manner (possibly with a category tree). I did a quick search in MediaWiki, but it's explanation was a bit confusing - unclear.

After some trial and error, I figured it out, so here is a quick tutorial on how to do exactly that.

Suppose this is the category structure we want to establish.

Don't we love it when Google takes over a product, or competes against an 'inferior' product and makes it better? Yes - Of course we do. We applaud, embrace and adopt the new technology.

But this is not the same way I reacted when I heard the news that Google is starting to take on Wikipedia. I was sort of saddened, and confused. I didn't really know what this meant. Wikipedia is an effort to create an online encyclopaedia - knowledge sharing - a way to get useful, pertinent information quickly. Isn't that exactly Google philosophy as well? Then why in the world does Google want to compete with it? Are they feeling insecure that a lot of searches reveal a relevant link to a Wikipedia article – within the top 10 results?

In my opinion
