Here's a podcast of the talk Dries and I gave at Drupalcon where Dries and I introduced Acquia.
I've spoken a lot in public, and am quite comfortable in front of a crowd. (In fact, I enjoy it.) Despite this, I think I was really trying very hard to please the Drupal community, and I must have been more nervous than I usually am. (Now, I have been accused of talking at "T1" speeds before, but I usually try to slow down.)
