:) Sorry.

In 2006, Craigslist's CEO Jim Buckmaster said that if enough users told them to "raise revenue and plow it into charity" that they would consider doing it. (source: http://blogs.zdnet.com/BTL/?p=4082 ) They really do listen to their users and the reason there is no advertising on Craigslist is that no one is asking for it.

A single banner ad on Craigslist would raise at least one billion for charity over five years. They could put a large "X" next to the ad, allowing you to permanently close it. There seems to be little objection to this idea. The optional banner is harmless, and a billion dollars could be enough to dramatically improve the lives of millions, save very real people from lifetimes of torture or slavery, or make a serious impact in the causes we take seriously around here. As a moral calculus, the decision is a no brainer. So we just need a critical mass of Craigslist users telling Jim that we need a banner ad on Craigslist. Per a somewhat recent email to Craig, they are still receptive to this idea if the users suggest it.

The numbers involved are a little insane. Fifty thousand people should count as critical mass, which means each person could effectively cause $20,000 to be generated out of nowhere and donated to charity. My mistake last time was doing it as a Facebook group rather than a Facebook fan page, where the more useful viral functions have moved. This time I would also drop the money on advertising to get an easy initial critical mass.
