Which? The Dropped D, or open?
I've always thought of open tunings as Keith Richards' tunings. 
Hate the users, not the tunings.
I'm referencing the talentless hacks from the hard rock radio stations who you see in guitar player fretting with a single finger.
"phoebe" from "friends" originally played "smelly cat" that way but quickly learned how fret proper chords in later episodes.
She has my gratitude.
I went through an entire issue last year and only one picture in the entire magazine had someone fretting a proper chord........and it was a doug marks advertisement.
