Understanding how content is organized in a wiki
Content in a wiki is what words are to an encyclopedia. Taken as a lump of words, an encyclopedia represents an enormous amount of information. But in a lump, it would be awful to look at and difficult to use.
So, the words are organized into articles, illustrated with pictures and other visual information. And those articles are further organized into volumes. Once this is complete, an encyclopedia can be a joy to use.
In wikis, content is likewise organized and illuminated with pictures and references. But the units of organization are slightly different. Rather than articles and volumes, wikis have pages and spaces.
