You mean the BitMessage secret forum or the one on that .bit web site?

All this conspiracy nonsense is just that, nonsense.  It is just some people who have similar interests and believe in the promise of the bitcoin technology.  People meeting, discussing business and improving their offerings is a good thing.  Nothing changes in the protocol, the people I saw who were attending on the list wouldn't abandon bitcoin and sell their coins (no matter how few or many they control).  At worst someone may get a good idea about a new product. 

And, btw, this so called "elite" moniker is just a ridiculous meme.  They just wanted to make it sound exclusive to entice people to come.  Since it is difficult to know who is behind what address/group of addresses, inviting so-called "whales" to meet on a nice island is a crapshoot.
