One of the first bots used on the World Wide Web. It was originally developed to track the Web's growth and was designed by Mathew Gray. At first it counted only Web servers, but was quickly redesigned to capture URLS. Its database of hyperlinks was called the Wandex and was the first Web database. The Wanderer created a furore because early versions caused network degradation. Its appearance coincided with the first arguments about whether such bots were a good thing for the Internet. It has now passed into history.
