BusyBug refers to http://www.busybug.com/ This url was first registered in 1998 by Michael R. Kalember, because firstly it sounded cute and would be easily remembered, and secondly because he often is such a 'busy bug'.
The primary purpose of the site is to help him organize his life into an online presence. This way he can share with other people, like his family overseas, friends, colleagues and even potential clientele. Also, by putting his life details online, he attempts to share his information with the rest of the world and in some small way contribute to the vast amount of seemingly useless garbage, which you and I must sort through everyday, as we surf the net.
