In the past week or so, a meme has circulated on the Web: "Tiananmen + Twitter = Tehran." But it's not just about the so-called "Twitter Revolution." That's a nifty catch-phrase -- the YouTube election, the Facebook effect, etc. -- for many in the mainstream media who are still trying to understand how people live their lives in this social networking age. In this world, a tweet from Canada leads to a Facebook fan page created in the United States, which then leads to a YouTube video from Iran. But these platforms are merely tools that allow people to connect over ideas. A more accurate equation, said Ho, who teaches information technology at Indiana University Purdue University Indianapolis (IUPUI), is "Tiananmen + Web = Tehran."
