The World Cup, all manner of movies, and the abbreviated term HMU ("Hit Me Up") dominated "discussions" among Facebook's 500 million users in 2010. That's according to the social net's "2010 Memology" report, which dissects a year of status updates. "What we share, apparently, are big world moments (World Cup, Haiti and the rescue of the Chilean miners), playtime (shorthand for hanging out, movies and games), coveting Apple products and the future (although most status updates seem to be all about the present)," reports MSNBC.com.

Year-over-year, the fastest growing trend was the use of a new digital shorthand for people to ask their friends to hang out. "Standing for 'hit me up,' the acronym was barely used last year but grew suddenly and steadily throughout 2010, especially during summer breaks and weekends," explains Lars Backstrom, a Facebook data scientist and report author. Other popular topics included teen crooner Justin Bieber; the earthquake in Haiti; the iPad and the iPhone; the Chilean miners; and the lyrics from B.o.B.'s "Airplanes."
