Snowden offers some tweaks to improve Twitter

 Edward Snowden offered the world details of US mass surveillance programs. Now, he’s offering Twitter CEO Jack Dorsey his thoughts on the social network.

In a video chat on Tuesday, Snowden said he uses Twitter in a “crude” way, in part to keep other tweeters safe. He searches for information he’s interested in but doesn’t follow other accounts, except for @NSAgov. The reason: following other users might prompt US authorities to take an interest in them.
