In walks the early Curators. Arianna Huffington is a curator. Her 'Huffington Post' editorial team picks and chooses what to feature on their home page. Mixing their journalistic editorial work with their hand-picked bloggers and with the best content from around the web. Michael Wolff's 'Newser' is as well. Perhaps the earliest Curator was Matt Drudge with 'The Drudge Report'.
In the Olde Days they were called Editors, and some were helped by Sub Editors.
