He tweets about eats, family, and friends. He invites followers to his "Jasoncam" for live newsroom video chats. He pokes fun at his co-workers in public. For sheer speed in achieving social-media critical mass, it's hard to beat WCCO's "Good Question" man. On August 6, National Cheesecake Day, he tried a little crowd-sourcing for his nightly segment when he tweeted, "How do you get a 'day' anyway? Good Question at 10. (Anyone have power to declare DeRusha Day?)" Within a few days, people who followed him on Twitter (@DeRushaJ), and who had never met him, propelled that idea forward. Minneapolis graphic designer Dusty Fields created a DeRusha Day website. Editor and writer Max Sparber launched an online petition. By late afternoon on August 6, DeRusha was down at the mayor's office, tongue planted firmly in cheek, seeking paperwork to get his day. On September 16, he got the news: Mayor Rybak had declared September 21 Jason DeRusha Day.
