actually he was obnoxious, and people were uncomfortable talking to him, and they kept trying to recap everytime he starts rolling his eyes or winking to the camera.
He even jumped around commenting on some guy's shoes.
If you haven't seen all that, then watch the video again.
ummm...I was in the interview and I wasn't uncomfortable at all. It was actually a ton of fun and as I walked around with Rory watching him interview others, they were all having a great time too.
Maybe you're just reading a bit much into it, but speaking as somone both interviewed and as a spectator, I think Rory did a great job and that he does a great job at getting tech guys to just talk to the camera in a relaxed way.
Here's the links to some of the other XNA sites I mentioned in the video. There are a lot more community sites and content than these, but going to these sites is kind of like finding one of the major on-ramps to the XNA community highway.
