|Granted, I've never played to a crowd like this.|
Or maybe, just maybe, I'm an irredeemable show-off.
I wrote the main post for this Thing, and a lot of my thoughts are already condensed into that post. Most of my good advice is over there, but one thing I haven't said before is that a sure-fire way to feel better about presenting is to know your subject matter well. If you're talking about something you've done, then it's hard to be tripped up: you were there, you know what happened, you know what the reasoning was. Maybe that's why I prefer professional presenting to academic presenting...
I've been lucky enough to have the opportunity to speak at quite a few events in the last year. Some of those were conferences and events I'd applied to speak at, and a couple have been invitations from organisers. Being involved in a number of different projects and groups means I've had quite a few things to say!
As for attending conferences, I've enjoyed that a whole lot more since I've started to get to know more people via Twitter and other social media. I wrote about that recently here.
Lastly - organising. Organising events is hard work. That's really all I have to say right now ;)
