Frederic Filloux writes about such curated and algorithmic sites as Techmeme and Mediagazer as they attempt to sort through the work of others and ensure the end-user consumes the original material. (Self-serving disclosure: I never try to usurp so much of anyone's work that it isn't worthwhile to click to it from here.)
But he's far less flattering about places like Huffington Post and its trait of taking involved and expensive journalism and flattening it into a digestible, self-contained post that sufficiently satisfies the reader and economically deprives the original source of its audience and revenue. Yes, he says, those bloggers link out to the original but write so extensively that it's not needed.
Filloux believes it's going to be necessary for publishers to thank the good aggregators and find technological ways to protect themselves from the "looters."
