In reply to Paul.

I suppose it was somewhat useful in terms of knowing a bit of something about how WordPress is used (or, maybe how directly involved WP-using-people are with WP). Aside from that, IMO, it was a waste of my time and theirs. If you don't ask the right questions, you're not going to get the right answers. Seemed more like a source for some stat-fodder for a keynote to me.
