We had a Microsoft Corp visitor in town over the last week - the unique and incomparable Mr. Vittorio Bertocci. My colleague Linda had the pleasure of touring and visiting many of our enterprise customers with him, talking up the core .NET 3.0 pillars (WCF, WF and Windows CardSpace.)

A persistent question prompted the following cartoon. Lifted shamelessly from Vittorio's blog post. I didn't know you could draw, dude! smile_regular 

While we take a gentle dig and laugh at ourselves, this does underscore the point that we need to do a better job at helping our customers truly understand SOA. 

PS: I am reminded again of a somewhat intense discussion a year back regarding service orientation, SOI and SOA by some of Microsoft's illuminaries.
