Love this exchange between William Shatner and Commander Chris Hadfield, currently orbiting Earth on the International Space Station:
@cmdr_hadfield Are you tweeting from space? MBB
— William Shatner (@WilliamShatner) January 3, 2013
@williamshatner Yes, Standard Orbit, Captain. And we’re detecting signs of life on the surface.

* At Shatner’s page, he says “MBB”, which appears in a lot of his tweets, stands for “My Best, Bill”
