Lost "Loose Ends"

IGN has a very long article about the Top 50 Lost Loose Ends with a discussion about each. I think they've hit on pretty much everything that's been bothering me, including:
#32: The Supply Drop
#31: Why Couldn't Desmond Leave?
#26: Libby
#24: Michael & Walt
#21: Christian's Body
#8: Locke's Legs
#5: The Unusual Connections Between Castaways
