We can reasonably debate torture vs. dust specks when it is one person being tortured versus 3^^^3 people being subjected to motes of dust.
However, there should be little debate when we are comparing the torture of one person to the minimal suffering of a mere millions of people. I propose a way to generate approximately one billion dollars for charity over five years: The Craigslist Revolution.
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. I have more recently emailed Craig Newmark and he indicated that they remain receptive to the idea if that's what the users want.
A simple text advertising banner at the top of the Craigslist home or listing pages would generate enormous amounts of revenue. 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 or make a serious impact in the causes we take seriously around here. As a moral calculus, the decision seems a no brainer. It's possible that some or many dollars would support bad charities, but the marginal impact of supporting some truly good charities makes the whole thing worthwhile.
I don't have access to Craigslist's detailed traffic data, but I think one billion USD over five years is a reasonable estimate for a single optional banner ad. With 20 billion pageviews a month, a Google Adwords banner would bring in about 200 million dollars a year. Over five years that will be well over a billion dollars. With employees selling the advertising rather than Google, that number could very well be multiplied. An extremely low bound for the amount of additional revenue that could be trivially generated over five years would be 100 million.
I'm very open to other ideas, but I think the best way to assemble a critical mass of Craigslist users is via a Facebook fan page. Facebook makes it very easy to advertise Facebook pages so we can do viral marketing as well as paying Facebook to direct people to our page.
50,000 users would surely count as a critical mass, meaning that each member of the Facebook page effectively created $20,000 for charity. I don't think there has been any time in history where a single click had the potential to do so much good, and the disbelief that this is possible is the main thing that our viral campaign would have to overcome. After the Facebook fan page got beyond a certain number of users, we could more aggressively take the campaign to Twitter and email.
Are there any social media marketers in the house? The first step is deciding what to call the Facebook page; it's limited to 75 characters.
It's time to shut up and multiply. I will match the first $250 donated towards the advertising budget for this, more next month depending on my personal finances. If anyone independently wealthy is reading this, $20,000 is probably enough to get the critical mass of users this week.
I welcome all of your criticism, especially as far as the mechanics of actually making this happen. As far as how to optimally distribute money to charity, that is very much an unsolved problem, but I think it's one that we can mostly worry about when we get that far. I also expect Craig and Jim to take a leadership roll as far as the distribution of the money goes.
Also see previous discussion.
Can we include save the world funding advertisements on Less Wrong? I don't know how much that would be worth, but it could give us more credibility when we say that CraigsList (or Wikipedia) should do it. The credibility would be especially useful if we are actually talking about saving the world, and not just supporting the far less effecient charities supported by the general public.
Why not just start a fund that takes ad revenues from any site that wants to join. Less Wrong could be the founding member but any site that wanted to could direct ad revenue to the fund. A lot of sites don't make enough to bother- a few dollars a month. But if you get 10,000 small blogs and a couple hundred large ones... thats a decent sized fund. And once the system is already in place then it gets easier to convince larger sites to join. There is a norm of sites giving their ad revenue to charity, etc.
