This weekend just past, I gave a presentation to about 20 odd people on the joys of Nagios, the open source server and network monitor.
This is probably the first bit of proper public speaking that I have done in a very long time.
Before I actually gave the presentation, I was so nervous, looking round, catching glimpses of other peoples presentations, vision based tracking, rapid web service development in rails.
I just thought, wow these people are really serious about this, should I even be here?
The answer was, hell yeah, the people in the room (including the authors of the two topics ^^^) obviously wanted to hear something about it otherwise they would be out getting coffee or something similar.
So a scary experience turned out to be really worthwhile and a great way to meet new people, BarCamp '09 here I come (just need to figure out a topic!)
PS once I started speaking I was fine, the most of the nerves left me, except of course when my remote started to misbehave....
