In this week's career chat, Marc Samson talked about Pressfolios, a new Web application that helps journalists build and manage an online portfolio of their news stories.

Samson, who is Pressfolio's co-founder, talked about how journalists can benefit from the site and why he created it. (Currently, the site is in private beta, but Samson walked through some of the features in the chat.)

Additionally, Samson talked about what makes a good online portfolio, how to create one and why they matter. You can replay the chat here:
