"Closed as duplicate" is such a frustrating experience with SO, especially since the canonical answer for the original post so often has so little to do with the supposed "duplicate" post, other than a superficial similarity in how the question is posed.

E.g.:

Q1: I'm trying to do x and it isn't working. A1: You're missing a comma in the list on line 7.

Q2: I'm trying to do x (and I've checked all of my commas), and it isn't working. A2: Closed as duplicate of Q1.
