One interesting point here is that WordCamp US should prove a motivating factor to make the WordPress Foundation a much more serious endeavor.

DrupalCons normally host 3,000 people and that requires a team of around a dozen from the Drupal Association working year-round to host the event.

We got sponsorship pitches in July 2014 for the event just finished in Los Angeles.

Hosting 2,000 people is a job for pros.
