Behold the biggest topics on Facebook, Google, Twitter, and Yahoo in 2013 -- you have no one to blame but yourself We are what we search for. Whether that’s a hopeful pronouncement or a troubling one, I’m not sure yet. I’m leaning toward the latter.This is of course the time of year when the major data collection machines — better known to us mere mortals as search engines and social networks — publish their year-end summaries.[ For a humorous take on the tech industry’s shenanigans, subscribe to Robert X.

For the rest of us, not so much. Down the YouTubeYouTube served up two lists for 2013: its most popular music videos and its top “trending” ones, half of which are also music videos. (If someone out there can explain the difference between trending and popular, I’m all ears.) Regarding the music portion, South Korean sensation Psy scored the top slot with “Gentleman M/V,” a video so awful I actually started to miss “Gangnum Style.” But thank God for Psy, because otherwise the top two music videos for 2013 would both be from Miley Cyrus: “Wrecking Ball” and “We Can’t Stop” (but we really wish you would). The top two trending YouTube videos both hail from Norway: “What Does the Fox Say?” by pop band Ylvis (not to be confused — ever — with Elvis), plus yet another version of “Harlem Shake,” this one performed by a Norwegian Army platoon. Yes, Norway has an army. No, we don’t care what the fox says, thank you. But apparently somebody does; that truly insipid video was watched nearly 290 million times.Kinda makes you long for a zombie apocalypse, doesn’t it? The year in Yahoo Yahoo also served up its list of top search terms for 2013, this one dominated by celebrities. Number one on the hit parade? Yes, the gal who made the term “twerking” mainstream. Proving that outrageousness gets you attention, if not critical adulation, Cyrus wrested the top spot from a preggers Kim Kardashian. Also in the top 10: Selena Gomez, Kate Upton, Amanda Bynes, and Justin Bieber. At age 27 (67 in Mouse years) Bynes is the oldest of that crowd by six years.Yahoo also provided a look back through its top searches to the year 2001. The winner by a landslide: Miley Cyrus’s spiritual godmother, Britney Spears, who snagged the top spot four times in 13 years. In the process, she also proved what most of us have already suspected: Yahoo’s audience is primarily teenage girls and dirty old men. Tweet nothings Surely there are signs of intelligent life on Twitter? Well, yes and no. The most retweeted item concerned the death of “Glee” star Cory Monteith, originally sent by his co-star/girlfriend, Lea Michele. The second most retweeted news concerned the death of “Fast and Furious” star Paul Walker. The third was the announcement by One Direction member Niall Horan that he just turned 20. (I know what you’re thinking: I’m too old for this. Man, I hear ya.)At Facebook, the most talked-about topic was not technically a living or a dead celebrity; it was the newly crowned Pope Francis. Also in the top 10: the royal baby, the Boston Marathon bombings, Nelson Mandela, Margaret Thatcher, and (inevitably) Miley Cyrus.When Facebook serves up the least frivolous list of topics, you know the planet has issues. The Goo-gods must be crazyI left Google for last because, well, it’s Google’s universe; we just feed its insatiable need for data. Seemingly just to show off the sheer enormity of the information it collects, collates, and monetizes each year, Google didn’t publish one or two or three top 10 lists for 2013. It published 80 of them, everything from the top trending searches (Paul Walker) to the top workouts and exercises (the Insanity Workout).A small platoon of sociologists could probably mine this data for years, but some of the highlights include the most searched for endangered species (tiger), Internet animal (grumpy cats), dog breed (bulldog), beer (Blue Moon), and celebrity pregnancy (Kim Kardashian outbumped Kate Middleton and Megan Fox). In the “what is” category, twerking is number one (naturally), followed by ricin, which happens to be what you’re tempted to take after spending too much time researching twerking. Curious Googlers also want to know what is DOMA, gluten, sequestration, Obamacare, lupus, and Snapchat.Strangely, the ubiquitous Ms. Cyrus only snagged the top spot in two of them: most searched-for person and celebrity breakup. OK, three if you count most popular GIFs (twerking). What, me worry? What conclusion can we draw from all of the above? I think it’s pretty obvious the Internet population is getting younger and more international. It’s also getting way sillier.Though serious topics made some lists (Nelson Mandela, Obamacare, natural disasters), the likes of Edward Snowden, the U.S. government shutdown, the worsening of the global climate crisis, nuclear threats from crazy dictators, and other important news failed to grab much attention.Maybe 2013 marks the year the Net fully transformed from an information medium to an entertainment one. In any case, it will soon be over, and that’s a good thing. May the searches of 2014 prove a bit more substantial. What did you search for in 2013?
