I’ve gained incredible amounts of knowledge from the Web. Being a self-described “knowledge whore”, I’ve spent countless hours on sites like Wikipedia and howstuffworks.com as well as other sources of knowledge like blogs, newsgroups, and forums. Almost without fail, though, every time I find myself digging deeper into a topic, I quickly realize that the topic is WAY more complex than I had imagined it to be. Try it sometime. Pick a topic and Google it. For even the most obscure topic, the sheer vastness of relevant information on the Web is mind-boggling.

I realized today that even though the Web has given me volumes of knowledge and wisdom, above all, the Web has taught me this:

You don’t know what you don’t know.

The Web bombards us with this lesson because it’s so damned efficent at information retrieval. In minutes we can open gateways to knowledge sources that might have taken hours or days before. More importantly, though, the highly-linked nature of the Web supports a breadth-first search pattern of knowledge gathering. You might be reading about sub-topic A and in the middle of a paragraph follow a link to sub-topic B and so on. I’m sure you’ve done this plenty of times. While your initial intent may have been to perform a linear search to ascertain information on a specific topic, before you know it, you’ve spent an hour reading about 10 different sub-topics. In one hour, you’ve gotten a broad, but relatively shallow understanding of several sub-topics.

If you had been performing research thru offline methods, you would have found an information source (a book, news article, thesis, etc.) on a single sub-topic and digested it thoroughly before continuing on to the next source. This pattern of information gathering is more similar to depth-first search. Using this method, in the same time as above, you may gain relatively complete knowledge of 2 sub-topics, but not even realize the existence of the 8 other sub-topics that you would have encountered if you had followed a breadth-first search pattern. In other words, you’ll know more about less. With the Web, you’ll know less about more. The curse of the latter is that you will have learned of the existence of many more topics which only further increases the magnitude of how little knowledge you have.

Anyway, it’s late and it’s likely that I’m just rambling, so I’ll cut this post off now. In conclusion, even though the Web has given me tons of knowledge, the most valuale knowledge it’s given me is the realization of how little knowledge I actually have. My guess is that by the time I’m an elderly man, instead of feeling old and wise, I’m going to feel old and dumb. Very humbling…
