I think for first time speaker that might warrant extra points - having spoken to enough other speakers at code camps and user groups it has been my experience that for many people it's a lot of stress for them to get up there that first time....and after that a number of them are hooked on it :)
I've never been nervous except when I was a last minute replacement for Rocky Lhotka at a code camp when he got sick and they had me speak in his time slot....that was a little odd, walking in there and they are all expecting Rocky and they get me instead! Fortunately for me, once I explained (to probably the 3 people who didn't already know I wasn't Rocky) that I wasn't Rocky and I wasn't going to be talking about CSLA, only 2 people left the room to go to another presentation. The rest stayed to hear me talk about dynamic code analysis with Visual Studio 2005.
