Jack comments on The Craigslist Revolution: a real-world application of torture vs. dust specks OR How I learned to stop worrying and create one billion dollars out of nothing

I love the first one. My alteration:

Help Craigslist Save the World

[childofbaud]

Slight rewording: “Save the world with Craigslist”.

This rephrasing puts the reader at the forefront rather than Craigslist (while maintaining the collaborative aspect of the venture) and reduces the number of verbs to one.
