Over the last several months we have mentioned how minimalist micro-blogging service Tumblr has attracted traditional media outlets. The New York-based startup has begun providing publisher-friendly features and even managed to snag former Newsweek editor Mark Coatney, who serves as a liaison for traditional media.

Today, National Public Radio (NPR) became the latest media group to join Tumblr, and I spoke with senior strategist Andy Carvin to find out how the organization plans to leverage the quickly growing platform.

Today Howard Fineman, a reporter at Newsweek for 30 years, announced he's leaving the beleaguered weekly to become a senior editor at The Huffington Post.

Newsweek has been struggling financially and The Washington Post Company sold the magazine for a small fee and its debt in August. The buyer was Sidney Harman, a businessman and philanthropist.

Tumblr is quickly becoming one of the Web's most popular and unique platforms on which to share and discover interesting content of all media. According to Tumblr, over 5.3 million posts are made each day by the service's over 7.5 million users. Posts are passed on over and over through Tumblr's "reblog" feature, but at such a high volume it's easy to lose track of where content originated. Tumblr hopes to solve this dilemma with some new attribution functionality launched earlier today.

A few weeks ago we reported on the glut of traditional media publishers that are seemingly flocking to the wildly popular micro-blogging service Tumblr. Now it seems Tumblr is also attracting the employees of these media outlets. Mark Coatney, editor at Newsweek and the man behind the magazine's Tumblr, Twitter and Facebook accounts, has announced he is leaving the publication to join the Tumblr team.

Traditional media's first major adoption of Web 2.0 came with Facebook, as outlets syndicated their content on the popular social network by way of fan pages and official accounts. Then, Twitter went mainstream as writers, editors and the media organizations themselves signed up, sent out links, and chatted about related topics in 140 character bursts. Now it seems traditional media outlets are flocking to another service - one that is almost a hybrid of the others, allowing for short-form posts, but with richer format.

What's the new trend among legacy media? Why it's none other than Tumblr.

Today is so-called "Super Tuesday" in the US. Voters in 24 states are heading to the polls -- including in large population states like New York, California, and Illinois -- to decide who get to face off for the job of US president as the nominees of the Republican and Democratic parties. After the votes have been counted tonight, 52% of the Democratic and 41% of the Republican delegates will have been awarded, and it may be that we have a clearer picture of who those nominees are.
