Better yet: Offer en_CA, en_GB, en_IE, and en_US, with appropriate flags.

(Bonus point for fr_CA with the CA-QC flag)

But then where's the flag for Liberia and Belize and Singapore? What if I'm in Indonesia and you don't offer an Indonesian option but I know enough English to get by - what country's flag should I click?

Just don't use flags, man. It's ridiculous that this is even still a discussion.
