In this week's career chat, we talked with Mark Coatney, director/media evangelist at Tumblr. Coatney began using Tumblr when he was special projects editor at Newsweek.com and has since learned how various news organizations are using the tool to share content, advance their coverage and reach new audiences.

Coatney explained how journalists can use Tumblr to advance their careers and the work they do, and he shared examples of news sites that are using the tool in innovative ways.
