I always feel uncomfortable speaking when my talks are being recorded. I have a particular style that's a little unorthodox to speaking. I get all professional when a camera's around, this also means that I feel less comfortable talking freely about issues that may have wider implications. I guess that's not so important for wordpress, but I'm talking at DC4420[1] next week on evading antimalware defences and that's not something I'd really want to see put up on youtube for obvious reasons.
