Think back for a moment to the early days of the Internet when domain name registrations were free. Imagine how rich you would be if you had thought to reserve “internet.com”, “business.com”, or any two or three letter domain name for that matter. Twitter attempts to limit reservations by requiring a unique email address for each sign-up. That is circumvented by using the Google “plus sign” email trick. Simply append something (your new Twitter ID for instance) to your Google email address like stiennon+itharvest@gmail.com. Gmail treats that as stiennon@gmail.com but Twitter thinks it is unique. It turns out you can just make up any old email address and Twitter will allow you to create a new ID.
