Barack Obama has an interesting promotion to announce his selection of a vice presidential candidate. In an e-mail to supporters, Obama is having people sign up to be the "first to know," courtesy of an e-mail or a text message. As near as I can tell, pretty much everyone is signing up, meaning nobody except the first person who opens his/her cellphone or e-mail is going to be "the first" to know.
Basically, you're the first to know in the same manner as if you watched it broadcast live on CNN.
It's worth pointing out, though, there is no privacy notice at the sign-up site, so it's anybody's guess where your e-mail address and cellphone number will end up.
He'll get good mileage out of the gimmick, though, as this post attests
Journalists scoff, but I bet you're all signed up too.
