I experienced the power of the Blog for the first time last week.  An entry I wrote concerning HTTP Send Port timeouts and message re-transmits came home.  I got an email from somebody in my employer's government division regarding my post.  The 3rd party vendor they use for a procurement system has BizTalk as part of the solution.  they were seeing multiple message posts to a web service.  The tech support guy at the 3rd party vendor sent them a link to my blog.  The government division folks recognized my name and emailed me.  A short teleconference later and the problem was understood and solved.  Small wide world.
