Seeing clearly?

Google's Gmail has a new service, just rolled out Monday: Google Goggles. It basically serves as an optional filter for those times when our internal filters aren't quite as strong. This nifty service aims to help prevent users from emailing when they're not thinking clearly, by requiring completion of some simple math problems in order to send an email at night on the weekends (or whenever you specify). I've seen the sorrow that can result from emails sent unthoughtfully, even if the person was not actually incapacitated by too much alcohol or too little sleep. Sometimes, just an extra step to make us think about what we're doing can be really helpful.

Of course, sometimes it's just annoying 99% of the time, so we end up turning it off right before the one time it would be helpful.
