Watch the 2009 Linux Plumbers Conference (Linux.com)

My main problem isn't that you can't do this perfectly, its that if you don't do it perfectly it has an impact on the people attending, who are paying to attend and whose companies are investing in their attendance.

LCA does this very well also, however if one more person ask someone talking to me to get a mic, I'd get annoyed, you've only got so much time at these things and really you should optimise for the attendees not the rest.
