I’ve been doing a lot of research on the use of audio slide shows, loitering in the digital corridors, so to speak, of the Guardian and the New York Times, among other multimedia laboratories. I like the new format’s many possibilities, but I do agree with conventional wisdom: Any show longer than two minutes becomes difficult to follow, falls down the slippery slope to boredom. (The incisive, indefatigable Mindy McAdams explains why.) But this slide show in the Times about a wrongfully convicted man’s first year out of prison, five and a half minutes long, is riveting. It’s the best of the many I’ve seen.
