Robert Scoble, please get back to work TwitteringWe remain impressed, if not dumbfounded, that Internet-obsessive videoblogger Robert Scoble talked his way into the absurd title of "managing director, Fastcompany.tv." We'll be even more impressed if he keeps the job, now that the guy who hired him has gotten the boot. But there's evidence that Scoble has buckled down a bit! Or slacked off, depending on how you look at it.Followcost, a website which quantifies just how annoying a particular Twitter user is, has adopted the "milliscoble" as a metric. One-thousandth of Scoble's average daily output on the 140-character-update service equals one milliscoble. By his own standard, Scoble has been falling behind; in the past 100 days, he's been running 32 percent below the 1,000-milliscoble mark. If it falls to zero, will he suddenly be three times as productive in real life? Nah. It will just mean he's shifted his timewasting entirely to FriendFeed.
