Let me put it this way: generally speaking there are things implicit and things explicit -- and at the hackmeeting the overwhelming majority of things to know and find out were implicit. It is in the nature of the self-organised event with flat, or, rather no hierarchies that those things that matter do usually not come with a large banner in human readable code that explains everything. There is not really a spokesperson, there are few figureheads, even fame is implicit, is something to be known and shared between insiders. What is to be found out is mostly based on direct human relationships. Everything else is largely a question of the 'vibe'.
