Whew, they just sent around the latest stats from our employee blogs at http://blogs.technet.com and http://blogs.msdn.com and those two sites combined had about 157 million hits. Now, keep in mind that doesn't mean visitors, but, still, if you told me three years ago that our blog sites would be getting hit that hard within three years I would have looked at you like you were doing crack.
By the way, we should thank the folks over at Telligent who make the excellent Community Server, which runs those blogs.
