So far this week, I've had contact with two 'famous':

First of all I've had a few emails going back and foward to Scott Guthrie, a pretty high-up guy at Microsoft who looks after the teams that produce ASP.NET, Visual Studio web bits and IIS). I've got a problem with the Web Application project that is currently in beta. I think it's a bug, so hopefully they can fix it for the next update.

The second person was a reply from Mark Russinovich, one of the guys behind Sysinternals. I reported an issue I'd seen with the BlueScreen Screen Saver when running remote desktop (it displays a funny error message).
