I have to agree with Foman says: at this point it's really hard to tell what the map really is, be it for looks or future content. While Bungie certainly has gone to great lengths to include real world ties in their games, we really just don't know enough to definitively say what the star maps are for.
And I share your feelings, Immpa! I count every one of you among my friends, even though I haven't even heard most of your voices. Unfortunately I have a concussion right now, so thinking hurts
As soon as I get better, I'll get back on my Hunter's Guide, and start following up on leads!
