If you believe that Facebook knows what people really care about these days, then 2010 has been the year of meeting up with friends, worrying about people in Haiti and Chile, and obsessing over Apple gadgets such as the iPad and iPhone 4.
The most popular term to show up on Facebook status updates was HMU, shorthand for Hit Me Up, often used to alert friends where you'll be in case they want to get together on the fly. Facebook says the acronym was barely used in 2009.
HMU was being mentioned 80,000 times a day by the end of summer, whereas it was found about 1,600 per day toward the end of last year.
The World Cup proved to be the most popular sporting event on Facebook, with as many as 1.5 million mentions in a day when the competition started up this past summer. On a lesser gaming scale, Farmville remained popular on Facebook, with the term "barn raising" being frequently mentioned in status updates (Games on Facebook cracked the top 10 trends list.).
On a more serious note, Facebook users kept a close eye on the Haiti earthquake and Chilean miners' saga. Within one minute of the earthquake's start, Facebook users were buzzing and they discussed it at the rate of 1,800 posts per minute at peak times.Movies was another hot topic among posters, though surprisingly (or not), Facebook makes no mention of "The Social Network" movie about Facebook CEO Mark Zuckerberg and the social networking firm's beginnings in its top trends list. Rather, it notes traffic spikes around premieres for films such as Toy Story 3 and Iron Man 2.
Rounding out Facebook's top 10 trend list via its "memology study" is iPad/iPhone 4, Justin Bieber (also see: Best/worst celebrity tech moments of 2010, Airplanes (largely in reference to the popular song "Airplanes" by B.o.B.) and 2011.
Last year's #1 trend on Facebook was the rather mundane "Facebook applications."
This month is a full of year-end lists from various online companies, including AOL, which found the iPad, Chatroulette and WikiLeaks to be among the year's most searched terms.
Just yesterday Twitter issued its Top 10 list, with the Gulf Oil Spill at #1, followed by topics such as Vuvuzela and Google Android.
