Buzzfeed gets a little love in this week's New Yorker article about the "death and life of the American newspaper".
The Huffington Post's editorial processes are based on what Peretti has named the "mullet strategy." ("Business up front, party in the back" is how his trend-spotting site BuzzFeed glosses it.) "User-generated content is all the rage, but most of it totally sucks," Peretti says. The mullet strategy invites users to "argue and vent on the secondary pages, but professional editors keep the front page looking sharp. The mullet strategy is here to stay, because the best way for Web companies to increase traffic is to let users have control, but the best way to sell advertising is a slick, pretty front page where corporate sponsors can admire their brands."
Here's the mullet strategy page on Buzzfeed. (Disclosure: I'm an advisor to Buzzfeed.)
