DotComGuy was the name of a former computing systems manager who legally changed his name to DotComGuy from Mitch Maddox in 2000. His project was to live for one year (beginning on January 1, 2000) without leaving his house in Dallas, Texas, ordering all food and necessities off the Internet and having them delivered. The house was monitored 24/7 and several video feeds were streamed online.
The project had a large number of sponsors including United Parcel Service, 3Com, Network Solutions, Piper Jaffray, Travelocity and an online grocer (now defunct) called GroceryWorks.com.
In the end of the project, DotComGuy legally changed his name back to Mitch Maddox. The domain, dotcomguy.com, is now in use by one of the investors for a new IT services business.
Every year on December 30 DotComGuy joins in a day-long irc chat session.
Maddox is now a Technology Evangelist for Ultimate Software.
