I attended Mike Rosen's (doesn't appear to have a blog, and the domain for the email address he gave doesn't appear to have a web site, but you can try searching for him by name and his company, Wilton Consulting Group, which will give you a ton of hits on presentations he's given) talk on Designing Service-Oriented Applications. It didn't quite meet my expectations. It was very high level, architecture-astronaut-y. Mike admitted many times to being a UML guy, and I got the distinct impression he hasn't written any code in years. Guys like him are the reason why I resist the title architect. If you don't have that same bias, it probably would have been a pretty good presentation. Mike's presentation skills are decent, and he does have a lot of experience. I was just hoping for something a little more practical.
