Washington Post goes into links. So not just its own take on politics but other people too on its new site, Political Browser. According to Publishing 2.0:
...Political Browser was born of a determined effort by The Post to get into the news aggregation game. Eric [Pianin, the Politics Editor] told me that interest in news aggregation extends to the highest level of The Post’s senior leadership, including Katherine Weymouth — they have been “fascinated” by the success of aggregation sites like Drudge, Huffington Post, Hotline, and others.
Beyond aggregation - post-google perhaps? - comes the “stamp of approval”, trust and context. Interesting.
