If you're curious about where Microsoft stands on employees' use of Twitter, take a look at Microsoft's "Tweeting Guidelines" (PDF). Few specific restrictions’re given; employees’re reminded instead to "use their judgment" and "to post sensibly and responsibly." The 10 questions on Microsoft's Twitter/microblogging FAQ mostly concern whether and when employees can announce their company affiliation and/or speak on behalf of the company. (In a nutshell: only if that's their part of their job.) Microsoft's stands out from many others' -- even other tech organizations' -- for its conversational rather than commanding tone, dearth of legalese and, frankly, implicit trust that employees won't do anything stupid, noted.
