Breathalyzer for your Gmail
Personally, I think this is a pretty neat little gizmo. Basically, in a blog post at: http://gmailblog.blogspot.com/2008/10/new-in-labs-stop-sending-mail-you-later.html
All you have to do is answer a few simple math problems, and boom, off it goes. I think the idea here is it gives you a second chance to reconsider your email. And, if you’re too drunk to think of an answer, perhaps you should wait till the next day to send it.
I think it’s neat, and of course, you can turn it on and off, so if anyone is complaining about that, well, they’re just silly.
