In this week's career chat, we talked with Matthew Keys, a social media junkie who has built extensive networks in journalism, public relations and communications. Keys, known as @ProducerMatthew on Twitter, has been blogging for seven years and was a former online content producer and manager at KTXL, a television station in Sacramento, Calif. He has since left the station and is now freelancing.

During the chat, Keys talked about how he uses Tumblr as a more visual extension of Twitter and as a way to archive his work. He also talked about how he's used the site to pitch his skills as a journalist to potential employers.
