Ron Jacobs did a talk on SOA patterns and antipatterns at the Upperaustrian .NET Usergroup last Monday. Ron is a long-term Microsoft employee and currently holds the position of Architect Evangelist. He is also famous for the MSDN Channel 9 ARCast podcast, which he is hosting. I have been listening to ARCast more or less since the beginning, and would strongly recommend it to everybody who is working with Microsoft technologies and enjoys listening to tech podcasts.
I also had the chance to chat with Ron after his presentation. It was really nice to meet him "in real life".
