Tweney.com - Understanding weblogs
After a couple of weeks, I realized that my weblog was turning into a useful repository of information. What was the URL for that nifty site about cork dolls? There it is in the weblog [6]. What about that news item on how many files are being traded over P2P networks? Right there [7].

In other words, I realized that a weblog could be a useful tool for personal knowledge management as well as for public communication. Because it's so easy to create and update a weblog -- the characteristic that has made blogging boom in the past year -- it's an ideal information capture device. Whenever you come across something interesting online, you can easily drop a link, a quote, and/or a comment into your weblog, and move on. You may never return to it, but it's there if you ever want to look it up again. Same with passing thoughts: Just jot them in the weblog.

Need to find something later? Use a search engine, either one built in to the blogging tool itself or, if your site has been indexed by it, Google.
