Black out at the Black Diamond

Hi Jesper, thank you for your comment. I'll try to reply at your observations.

A) How many people were actually let in?
Taking the numbers reported at http://www.dkbs.dk/centerside.cfm/menu/center/konference/148/billede/2.html, we have that the standard reception of the Black Diamond is (at maximum) 1200 people, a number calculated considering security reasons. Now, let's double it to 2400, because we don't want to waist our time with numbers. The fact is that even if 2400 people managed to enter at the Black Diamond party, 5374 people signed up on the Facebook page of the event: no doubt the organization has been very good to create a good hype around it! Now, probably not all the people signed on Facebook really planned to go to the party, but probably a few of them wanted to come with friends which were not on the list, so the number is a good approximation of how many people was reasonable to expect, also because there weren't other large events going on.
So 3000 people couldn't enter (usually you don't go to a concert and you leave after half an hour, so the majority people entered to stay, and not to leave after a while), and the organizers knew this before the party started.
That's the point I wanted to underline: it was better to make a list of participants, so as to control the affluence of people without creating expectation which couldn't be satisfied.

B) Does the number of security guards at the door imply anything about the quality of an event?
The number of the security guards is just an indicator, which underlines a certain disparity between what happened and what was expected. And I wrote "The lucky few who managed to enter were treated to enjoyable concerts, with light effects projected at 360 degrees", which is certainly not a critique to the quality of the event.

C) What about an account from organizers?
Before writing the article, I contacted the Black Diamond Communication Consultant, which told me that after a while people couldn't enter because for security reasons. In my opinion this doesn't give any additional information to the reader: it's obvious, and as I sad in point A), the organizers should have thought about it.

Regards,

Alberto
