From a recent Wired magazine article about Microsoft:"In fact, the 71,000-employee company now has more than 4,800 bloggers posting on every imaginable tech topic, from startups to SQL." http://www.wired.com/wired/archive/15.04/wired40_microsoft_pr.html
PS: Thanks to my colleague Gus who provided the pointer to this article...
Disclaimer: This is probably a very conservative estimate coz there might be many many more employees who might have blogs on other private blog site and also on live spaces etc... I guess the above number is TechNet and MSDN blogs (exludes me too :-))...
