Because our company executives are too busy mining our gold to perform menial tasks like web development, issuing PRs, holding meetings, sending out Twitter updates, running copies, cleaning restrooms, filing important legal documents, updating shareholders, etc...
In order to perform these tasks, a company has to have an office, a mailing address, company officers, company employees, desks, chairs, computers, phones, filing cabinets, files, restrooms, janitors, etc...
If you want the answer to any of your questions, you may be able to find your company executives. Just look for an unmarked panel truck parked outside a pool hall in one of our fine urban cities. They will be easy to spot because you are looking for a truck marked Two Men and a Truck of Gold.
