Here's a suggestion.. Let us hide things for others to see.. Let us place Easter Eggs of our own - something like dead ghosts but different - for our friends (or maybe anyone) to find. An alternative to this might be something like being able to write graffiti on a wall somewhere. Many times I've found some cool little hidden area I've climbed into (either buried away somewhere in the VoG, or up in some scaffolding on Mars), and wished that Bungie had put a dead ghost there. Then I wish that I could leave something there for someone to find someday.. It'd be cool to be told later that someone found it. Imagine groups running scavenger hunts across all of the worlds in the Destiny universe. That would kick ass.. (well, for those of us who enjoy hunting around the scenery).
