Using that logic (ordering them as on ABC Medianet), one could make just as strong an argument that the cast should be listed in the order of their cast bios here on the offical ABC Grey's Anatomy page.  That would put James Pickens Jr. ahead of everyone except Ellen Pompeo and Patrick Dempsey.  One could also argue that they should be listed based on what they're paid, since those figures were recently reported, in which case Isaiah Washington and Katherine Heigl could well wind up on the bottom of the list.  I really think that listing them in billing orderthe traditional method, as pointed out by the above responsemakes the most sense.  I won't revert it yet, hopefully some other people will add their opinions, so we can establish a better consensus?
