Okay, I have just 2 things to say to all streetpassers, especially new 3DS owners:
1. Set your country correctly! I know you don't live in Anguilla, you were just lazy and picked the first country choice instead of scrolling down to United States! I've got like 30 streetpasses with people who claim they are from Anguilla! That is not demographically possible in Los Angeles, unless there is an Anguillan enclave of immigrants that I have never noticed!
2. Do some of your darn puzzles! Yes, I know I'm an ambassador and I've had this thing since launch, but it seems that 9 out of 10 of all my streetpasses don't give me any new puzzle pieces! What are you using those coins for anyway? Downloading new DOA costumes? Purchasing the really crappy guns in RE:R raid mode? I doubt it!
