Hierarchy on its way out

A friend introduced me to del.icio.us a few weeks back and while I was initially a bit hesitant to use it (unlike her I'm not an early adaptor), I am now absolutely besotted by the concept.

Del.icio.us is a webbased feature which lets you store you favorite links and bookmarks online on the basis of semantic categories. Most of us organise our computer files and links in a hierarchical manner: we create files and subfiles to store them under.

For instance, if I am trying to hunt down a picture of a friend's party a while back, I would open a file called "LePew" then "Pictures" then "Olympus Camera" and then I need to rack my brains to remember when exactly this party took place, because I have stored all my private pictures by month. So if the party was in August 2005 I'd have to click on a file called "08-2005" to locate it. It's a bit of an effort, to say the least.

My weblinks were stored in a comparable manner. But del.icio.us now allows you to tag your links. For instance, if I was to store my own blog as a favorite, it would first of all be stored under its own name "Ubiquitous" and then instead of placing it in a file or subfile, I would simply attach tags to it: "blog, Pew, science, entertainment, ubiquitous, lesbian, Ghent, physics, life" etc... whichever term I would associate with this link. When I next try to find the link, I merely need to type in a few key-words to hunt it down, instead of trawling through a hierarchically structured directory.

What makes it easy, is that this type of storage is based on semantic and associative thinking. You don't need to remember dates or filenames. You simply think of keywords that naturally spring to mind when you yourself think of that file. And I'm becoming increasingly aware of just how associative my brain thinks. I rarely remember exact facts (which can be frustrating at times). But I do remember concepts, ideas, keywords,... that link into and out of others to connect the general dots and to see connections between otherwise unrelated or distantiated topics. I guess this is a common characteristic for people used to interdisciplinary environments and for conceptual thinkers. But what strikes me, is how different my keyword structures are from other people's.

Del.icio.us allows one to make "Tag Clouds" which is a visual representation of all your keywords. I've browsed the del.icio.us pages of several friends and they are generally very succinct and logical it seems, with keywords such as "blog", "music" or "fun". Whereas my tag cloud... well... see for yourself:
