PBS Arts Off Book put out this interesting, short video this week with some thoughts from a few leading minds in the digital journalism sphere (including Mark Luckie, the 10,000 Words founder and current manager of journalism and news at Twitter). The subject is all about how Twitter has impacted journalism and journalists’ role in using the service to source news and be a source of news. I wanted to pass it on because some of the points the speakers (Luckie, Jeff Jarvis, Craig Kanalley and Chris Anderson) brought up were important to think over, including the role of journalists as the filter for Tweets/breaking news and also the importance of realizing a lot of sources and people aren’t on Twitter or Facebook. Anyway, it’s only about 5 minutes long. Watch it.
