I moved this to the Strategy / Technique advice forum! ^_^
I feel awkward on camera, too... And I watch my footage back thinking I look so nerdy and awkward lol! But I think it's partly just an internal thing. Other people aren't commenting on my awkwardness, so maybe it's not as noticeable as I think it is -- or, even if it is noticeable, viewers aren't getting annoyed by it.

I've noticed that the camera gets less scary with each video I make, so I think talking to a video camera is something we can get used to with time and practice.
