As Mashable’s Christina Warren advised:

Public no longer means “public on Facebook,” it means “public in the Facebook ecosystem.” Some companies, like Pandora, are going to go to great lengths to allow users to separate or opt out of linking their Pandora and Facebook accounts together, but users can’t expect all apps and sites to take that approach. My advice to you: Be aware of your privacy settings.

The other complaint readers had when they weren’t asking technical questions was: What, exactly, does this have to do with journalism?

One reader, who called herself samatha3, wrote:

Just read this in an AP article: “Facebook CEO Mark Zuckerberg says the new tools will allow users to see personalized versions of other websites they visit. It’ll be based on the things they have shared on their Facebook profiles, such as their friends, bands they like or news stories they have liked.”

I don’t want personalized news! Part of the problem with some news sources now is pandering to a perspective. This Facebook idea has no place on a serious news site.

Another user, going by the name MissAnnThropy wrote, in part:

This is really a terrible idea. I like to think that the people at the WaPo get the fact that I want solid reporting, not a social experience. I have been proven wrong…

Narisetti said no editorial content creation had been sacrificed in developing the Facebook application, which was handled by the tech side of the paper. But, he pointed out, it is unfair for those who say they want to support serious journalism while visiting a free website to begrudge the Post’s promotion of its own content:

“The flip side is, we remain a free site and we have to be able to fund news generation, news creation, content creation activities, and the healthier we are as a company, on the business side, the more resources we have for a free site to be able to provide the content that we need to,” Narisetti says.

As the economic foundations of journalism has shifted, newspapers increasingly have make the argument that they are relevant and valued by others. And that’s all Narisetti says he is doing.

“I feel like part of journalism is to make sure that Washington Post content goes in front more people, ever more people,” he says. “If this allows me to do that, I feel like this is part of my job as managing editor.”
