Can government be run like the Internet, permissionless and open? Coder and activist Jennifer Pahlka believes it can — and that apps, built quickly and cheaply, are a powerful new way to connect citizens to their governments — and their neighbors.
Computer programmer Luis von Ahn wondered how else to use small contributions done by millions on the Internet for greater good. He put CAPTCHAs, those online puzzles to verify you're not a robot, to work by digitizing books and teaching foreign languages.
Social media guru Clay Shirky looks at "cognitive surplus" — the shared, online work we do with our spare brain cycles. While we're busy contributing to the web in our small ways, we're building a better, more cooperative world.
Founder of Wikipedia Jimmy Wales recalls how he assembled "a ragtag band of volunteers," gave them tools for collaborating to create a self-organizing, self-correcting, never-finished online encyclopedia.

<strong>The Australia-France-EU Proposal.</strong> This proposal for new marine protected areas "would conserve representative areas of biodiversity in the high latitudes of the Indian sector of the Southern Ocean," according to the Australian Antarctic Division.
The area of ocean set aside as a nature preserve could double or triple in the coming days, depending on the outcome of a meeting in Germany. Representatives from 24 countries and the European Union are considering setting aside large portions of ocean around Antarctica as a protected area. And the deal may hinge on preserving some fishing rights.
There are two proposals on the table: One would set aside huge parts of the Southern Ocean around East Antarctica; the other would focus on the Ross Sea, south of New Zealand.
The PSA test has been dissed a lot lately. The nation's preventive medicine task force, for one, says the test is so unreliable in figuring out who's at risk for deadly prostate cancer that most men shouldn't bother getting one.
