When you enable Mail Goggles, it will check that you’re really sure you want to send that late night Friday email. And what better way to check than by making you solve a few simple math problems after you click send to verify you’re in the right state of mind?
As you can read above and by the challenges bellow it really looks like a test to find out if you are drunk or under the influence of drugs. lol
This Plugin is kind of useless, but you can find some more with nice features. Learn about Gmail Labs in the official Gmail blog.
If we believe in the weakly SOL Noticias, this measure is destined to prevent drunk users of sendind mails that they can later, when sobbers, regret!!! LOL
Useless?
I believe you are confusing utility with complexity.
For example, the ms-dvr format, despite its added complexity, is of little to no utility.
This plugin*, while simple, can prevent several damage to social connections, personal image, and ultimately, your place in society.
*did we really forget the meaning of “plugin”, versus internal optional features?
