Do you use four-letter, three-letter, or two-letter codes? Why?
And 4-letter codes are dumb. They don't give you any useful information that doesn't need to be heavily processed. Two-letter codes are the best, imo, but I guess nobody uses them |:
A: "She's an IL."
B: "You mean ILE?"
A: "Yeah. IL."
C: "... ENTp? What are you guys talking about?"
