Google has just released Mail Goggles (do you have any idea how hard it is to not typo that as “Mail Googles”?), a new enhancement for Gmail designed to keep you from sending that 3 a.m. email while under the influence that you know you’ll regret in the morning, but send anyways. The Google Goggles work by requiring you to solve several math problems within sixty seconds before allowing you to effectively hit “send”.
