I don't consider my Facebook application (i.e. wall, timeline, groups, etc.) usage very high, but my Facebook messenger usage is through the roof. I don't even have any other way to reach most of my friends or contacts. I get the impression this is very common among people in their twenties. Alternatives like Google Hangouts, Snapchat, Line, WeChat, etc. don't have nearly as many users, at least among my social groups.
