NPR said it has named Farai Chideya, a correspondent and sometime host for News & Notes, to replace Ed Gordon as host of the weekdaily public affairs hour. The network will also add online interactivity to the show produced with African-American pubradio stations. Chideya is founder of the Pop + Politics website and former talk host of San Francisco’s KALW-FM who has worked for ABC News, CNN, MTV, Oxygen cable channel and Newsweek. Nicole Childers was promoted to e.p. NPR and Gordon swapped some finger-pointing this summer over responsibility for the program’s limited carriage.
