Given my last post, the word of the day is part of the rich vocabulary of domain names. The word is domainer - "a person who makes a living from domain name speculation or by purchasing popular domain names and filling the sites with advertising." Australia's best known domainer owns 600,000 domain names. The definition is from Word Spy, which is a pretty nice site, too.
Another nice one is typosquatter "A person who registers one or more Internet domain names based on the most common typographical errors that a user might commit when entering a company's registered trademark name (e.g., amazom.com)." Australia has a policy on registering misspellings as domain names - you can't do it.
