So if anyone wants to know how they figured out the exotic quest.

That site I linked above for the ARG is fairly unique per person it will give you 5 nodes and a huge wall of text. That text can be decrypted using some crazy code key analyzer thing which results in a JPG that's a square with those nodes on either side. The community found a way to easily submit your code, nodes, etc. 1,500 submissions later, they compiled the list and took the images and matched the nodes on either side resulting in a map of a particular room of the raid. Using this and some math/computer knowledge, they were able to piece some things together and figure out how to make it all work.
This is the 1st ARG that really had a direct impact on the game and it was a crazy one.
