From Mashable:

As the snow piled up on New Year’s Eve, Jersey resident Ravie Rave didn’t call a snow plow service to take care of her 65-year-old father’s walk — she tweeted at Newark Mayor Cory Booker, who showed up shortly with shovels and salt.

Booker, who has more than a million Twitter followers, is a regular man-about-town when it comes to the microblogging service (remember that whole thing with Conan?), but this level of responsiveness is extreme, even for the sometimes to-good-to-be-true politician.

And if you don’t follow Cory on Twitter, you really should. He is the most engaging politician I have ever found on there.
