Thanks Mendel - a few other comments from someone who has spent significant time in both communities.

DrupalCon moves around - one a year in North America and one in Europe (though now also exploring South America and other places) - much like the model for WordCamp USA (what used to be WordCamp SF). I think that's a better model than having the "premiere" event in the same place each year.

It also seems to me DrupalCon has a much larger budget than most camps - even, I would guess, San Francisco. (I attended DrupalCon annually from 2008 to 2013, and I've organized WordCamp Boston, but haven't ever looked at a budget for SF).

DrupalCon tickets for LA this year, for example, ranged from $450 (early bird) to $650 (onsite), plus separate tickets for any of the Monday training sessions, Higher-Ed summit, or Business Summit, which ranged themselves from $199 to $450.

Diamond sponsorships listed at $45,000, platinum at $30,000. In LA they expected 4000 attendees, in previous years they've had over 3000.

There isn't an equivalent of WordPress.tv, but many (most? all?) of the sessions from DrupalCon (and DrupalCamps) get recorded and posted online (YouTube, Internet Archive, or elsewhere), often embedded directly in the schedule after the camp.

I'd love to see BoF sessions at WordCamps, bringing together folks focused on large scale sites, on higher education, on marketing, etc.
