The Internet has not become the great leveller that it was once thought it could be.

When I was growing up in the U.S. in the 1970s, 35-40% of an average nightly newscast focused on international stories.

On Twitter, if you want to quote someone else, you say, RT, re-tweet, that person's name, and then what they said before. And it's a way of essentially saying, I'm not saying this, but my friend said this and I thought this was interesting.

The Internet is corporations all the way down.

Moments of crisis, like the shooting in Newtown, tend to produce brief spikes of popular interest in gun control. My research on media attention suggests these spikes are extremely short-lived, and that they may be decreasing in intensity.

Reddit names are unconnected to real-world identities and it's commonplace for users to create 'throwaway' accounts to reveal sensitive information.

Twitter is my main tool for ensuring news balance.
