Yes, folks, even speed bumps have Facebook pages these days. William David, an art student at Pratt Institute, e-mails The Local to point out a “Brake for the Kids” campaign he has launched as part of an effort to get the Department of Transportation to install a speed bump on East Seventh Street. Aside from setting up Facebook and Twitter pages, he’s advocating in the real world, too: Mr. David says that as part of his senior project, he plans to set up a booth near St. Brigid School this weekend to raise awareness.
