Who Runs is operated by a staff of four people. We write most of the articles, post daily news, take most of the photos, prepare most of the graphics, tend a server that transfers terabytes of data each month, and do the work needed to run the store.

A number of guest authors with expertise in specific areas have contributed articles to the website. They are acknowledged on the pages where their articles appear.

Who Sponsors is not financed by companies, special interest groups, or contributions from anyone. It is financed by advertising revenue, the same as most newspapers and their websites. We also make a small profit from items sold in the store.

We do not sell ads directly to anyone and have no intentions of selling ad space in the future. The ads that appear on our website are purchased by advertisers through the Google Adwords program or the Exponential ad network. These ads are then transmitted directly to our website by Google and Exponential. This allows us to spend our time creating content for our visitors. Allowing others to take care of the ads allows us to spend more time on what we do well and provides separation between the content that we write and our sources of advertising revenue.

If you see an ad on, that does not mean that we endorse the company or have any direct relationship with them. We have little control of the ads, but we do instruct Google and Exponential to block categories of ads that we believe are inappropriate for our audience and to block ads from specific advertisers that we believe are inappropriate or annoying.

If you appreciate the content that we produce, we would appreciate it if you would help us maintain our revenue by not using adblocking software when you visit our site. We spend thousands of dollars every week to produce the content and allow you and a worldwide audience to view it free of charge. Revenue from the ads is what makes this possible. If our ad revenue stops we would be forced to lay off our employees and close the website.
