Our Twitter Week in Review chart uses data collected and parsed for Ad Age by the What the Trend unit of HootSuite, the social-media management dashboard with more than three million users. (Last week's chart is right over here.) We're back today with Volume 9. Scroll down below the infographic for some context -- and watch for a fresh edition of our Twitter Week in Review each Friday.
- Social media and protests have spun up their latest self-reinforcing feedback loop in Mexico, where students have been objecting to media coverage of the presidential campaign. The movement started when presidential candidate Enrique Pena Nieto spoke at the Universidad Iber-Americana -- one of Mexico's top universities -- on May 11 but was shouted down by a vocal group of students, causing Mr. Nieto to cut his speech short. The heckling was downplayed by the candidate's team and the media, which has long been accused of bias, so 131 students took to YouTube to demonstrate their assembly and protest the media's coverage of the race. This led to real-life student demonstrations across the country, producing (like every event these days) its own hashtag: #MarchaYoSoy132 (roughly translated: "The 'I Am 132' March"). Incidentally, Mexico is seventh among countries who use Twitter most, with upward of 10 million users.
- Don't worry, though -- Twitter isn't only being used for social justice. There are still plenty of Justin Bieber fans trolling hard and bringing the party back around. "Justin <3" is exactly what it looks like: an army of teen girls' social ode to their "Boyfriend" (the title of the singer's most recent official single, which, aside from being his most adult and urban record yet, is holding steady at No. 9 on Billboard's Hot 100 singles chart this week).
- Speaking of mundane fan messages to pop stars, "Have a #SafeFlight1D " is nothing more than millions of girls hoping to feel closer to the five members of British boy band One Direction by wishing them a safe flight as they proceed on their world tour.

- It was a big week for TV-series finales, but for one in particular: the Fox series "House," which finished up its eighth and final season Monday night, making a huge social splash and taking No. 4 spot on the most-tweeted brands chart.
- The week's top memes were as unsettling as ever, with many Twitterers fondly recalling the things "#GrandTheftAutoTaughtMe." Grand Theft Auto (or "GTA" on the street ) is , of course, the video-game series in which users are empowered and encouraged to steal cars, kill police officers, and negotiate violently with prostitutes, all from the comfort of their sinking sofas. Perhaps most encouragingly, user @jcuuli tweeted that GTA taught her "How to take out my anger in a virtual world so I don't in the real one."
