Good question

I am thinking this is a good question.

"These days, when something in the world goes very wrong, it seems as if everybody learns about it first on Twitter and Facebook. In the minutes after homemade bombs turned the finish line of the Boston Marathon into a crime scene, terms such as #BostonMarathon shot to the top of Twitter's Trends list; across the country, office workers first learned of the attack when someone posted a message on a Facebook page. Social networks have become this generation's radio, the default conduit for the freshest information. As first responders treated the wounded and the minutes ticked past, news organizations began vacuuming up Twitter and Facebook posts from around Boston and posting it on their Websites, along with 'regular' text updates. A Vine video-snippet of a bomb going off near the finish line, knocking a runner off his feet, ended up embedded into dozens of blog postings. When a disaster strikes, and many of those same news Websites post 'live updates' that incorporate tons of social-networking posts, they face accusations of exploiting the tragedy in the name of pageviews and revenue. That's not surprising—long before 'yellow journalism' became a term, people have charged news organizations with playing up humanity's worst for their own gain. In the immediate aftermath of the Boston bombings, online pundits lashed out against Mashable, The Verge, Wired, and other publications that had posted live updates, accusing them of stepping outside their usual coverage areas for cynical gain. In the following piece, a number of tech editors-in-chief, including The Verge's Joshua Topolsky and Mashable's Lance Ulanoff, talk about their approaches to covering the tragedy."
