In Chile, a website called Poderopedia has recently been launched by Knight International Journalism Fellow Miguel Paz. A crowdsourced map of business and political power, Poderopedia aims to make connections between people more transparent. Paz explains how some of the powerful people profiled are also some of the site's best contributors, during this interview for the U.S.

Upon finishing a story, reporters once stowed away their source documents in a desk or filing cabinet. But today, reporters and news organizations increasingly put their primary sources online, to engage users with the facts and data behind the story.

At the Argentine daily La Nación, a team of data journalists is using DocumentCloud, an open-source project that hosts thousands of primary source documents from newsrooms.

Many journalists wonder how they can evaluate the impact of an investigation or a blog post. Here are some simple techniques to use:

1) Use Google advanced search:

• Place the permanent URL for the content you wish to monitor in the second text box
• Do the same with the title
• Repeat the same step for the subtitle or the short summary of the article.

In all cases, use the "narrow your results" tool to analyze the results for the last 24 hours.
