It’s a tale of two social titans on this week’s Mediatwits podcast. On Tuesday, select users were able to test out Twitter’s new dedicated news tab. An algorithm is used to determine which news stories are featured in the experimental feature. The tech company has struggled to attract more users lately and the “Featured News” tab may be an attempt to make the service easier to use. Whether or not the new service becomes permanent remains to be seen. But we can be fairly certain Facebook’s going to keep its native video service. The feature has come a long way since it originally launched as a test feature in late 2013. Often, the same video will get more views and faster on Facebook than on YouTube. But not everyone is happy about FB video. Earlier this week, Hank Green, a popular YouTube creator, wrote a scathing piece criticizing Facebook’s practices, including pirated video and how it counts brief views that are auto-played for viewers. Our special guests this week are Lauren Johnson of Adweek, Erin Griffith of Fortune, Selena Larson of the Daily Dot and regular Andrew Lih of American University. MediaShift’s Mark Glaser will host, with Jefferson Yen producing.
