A video shot at Costa Rica's Parque de la Democracia in San José has gone viral.

Periscope, the live-streaming video service, announced a big integration partner Tuesday: its owner, Twitter.

The account -- which already had nearly 150,000 followers in the first half hour and a million followers shortly after -- instantly became one of the world's top hacking targets, but will also allow U.S. President Barack Obama to tweet directly for the first time.

Nine years after the site launched, and two years after investors began demanding user growth, Twitter seems to have realized what lots of hardcore users learned the hard way long ago: that the great hallmark of Twitter, the unfiltered real-time feed, is psychologically untenable.

David Korenfeld, a high-ranking official in Mexico's cabinet, is the latest politician to be exposed by citizens on social media.

Following a formal request from Casa Presidencial, the popular short-message social network Twitter confirmed on Tuesday that it had removed a fake account that had been posing as the official profile of President Luis Guillermo Solís.

It really is the age of the selfie. Instagram announced Tuesday that 300 million people log into its site every month. That puts the photo-sharing site ahead of Twitter, which claims 284 million monthly active users on its official website.

"A los de Ayotzinapa les dieron Crunch," the account tweeted, a little pun on its namesake candy bar. Translation? "They crunched those from Ayotzinapa."

The Associated Press revealed more details Monday morning about Costa Rican involvement in United States Agency for International Development’s covert anti-Cuba operations, including the use of HIV-prevention workshops as fronts for recruiting pro-democracy activists.

While the court ruled in favor of the defendant, freedom of expression experts said the preliminary ruling does not necessarily signal a free-for-all when it comes to criticizing public officials.
