I felt that my own major session, a tutorial on building semantic web applications for government data, was very successful in this regard. I was originally disappointed with the registration, but discovered on the day that most people signed up for 'tutorials' in general, then attended whatever they liked. The room made it to SRO before the first coffee break, and many of the people there were from government agencies or contractors, as desired (many were from other places, but I'm not going to complain about that!).
Probably the biggest measure of success for this goal was the exposure in the Government Computer News. Senior Technology Editor Joab Jackson seemed to like my elevator pitch about the Semantic Web (though it only works for veerrryyy slloooww elevators) enough to repeat it in one of his articles about the event. In another article, Joab told me something I didn't know - that the report we generated in the tutorial is actually interesting to government IT managers, and would somewhat labor intensive without linked open government data.
GCN's 13 resources seems like an intentional flaunting of superstition, since one could easily come up with many more. I am flattered that one of my own pages made it to the list; many of the omissions are available there, and include US Gov XML and OEgov.
All in all (thanks to a great extent to Mr. Jackson's efforts), I think we managed to achieve some exposure for semantic web technology for government information managers.
