Siskel & Ebert at the movies

Roger Ebert, screenwriter and Pulitzer Prize-winning film critic, died on 4 April 2013, two days after announcing that the cancer he'd been battling since 2002 had returned. The worlds of journalism and film lost one of its greatest champions, and film lovers around the world lost a friend and mentor. As the announcement of his death swept the Internet, I watched as social media exploded in a simultaneous outpouring of grief, loss, and respect.
