On a Saturday in October 2009, "a synchronized burst of more than 4,300 demonstrations, from the Himalayas to the Great Barrier Reef," called the attention of world leaders to a single number: 350.

Their message was simple: 350 (as in parts per million of atmospheric carbon dioxide) = survival.

Of course, organizing the event was a little more complicated. And while 350 is about what happens to the planet offline, it couldn't have happened without the internet.

Slate's Farhad Manjoo explores Barack Obama's transition from a hyper-networked candidate to a 21st century president from whom, now, much is expected; The Nation's Ari Melber keenly notes that a recent Washington Post story slipped in the unattributed bombshell that the Obama campaign's email list topped out at some 10 million members; The organization known as the Obama-Biden Transition Project (I just love that name -- so very '70s experimental band, no?) has brought on someone perhaps best known in these parts as a blogger, Open Left's Mike Lux; and a good deal more.
