So how should an event like this be organised, an old idea I send to a group of peope that organised such an event:

Create groups that organise themselves depending on theme, hosts, country / continent. Make quarter groups, a couple of people that make sure a block of 8 hours is up to standards / up to speed.

Write up a little storyline and let them freak out on it with little clues and user participation instead of just a 24 hour slide show. Make sure the groups organise themselves and have a few deadlines for planning and linking up.

Off course the main problem is: you are relying on the users to make it happen but then again: you always are.

this way there is no inhuman pressure on anyone and it will probably be more fun and diverse.

I also think people who take a certain role or responsebility should either stick to it or handover the keys if they decide not to play anymore. Holding a event / community resource hostage sucks because it pretty much gives nobody the chance to make something happen.

I remember in 2002 XXX didn't do anything until it was pretty much to late and everybody flipped. The only thing XXXX should have done was give someone else the ability to work on the stuff we though was needed and people would have been happy and on time.

Don't want to play anymore? Give the keys back to the community and let them play :)
