I also browse Facebook whenever I'm on my laptop. It's almost instinct for me now whenever I want to take a quick break from whatever I'm doing. I noticed that a lot of people post food pictures now... I'm not really sure why food pictures have become such a popular post topic, perhaps because everyone loves food and we want to show it off? "Artsy" pictures with filters have also become more common. It's become much easier in recent years to take better pictures now that we have the technology for it.

There's also some subtle advertising on the right on Facebook with trending topics, though to be honest I don't really look much at it... I really only use Facebook to be connected with my friends but Facebook can also be used for posts by celebrities or sports, etc...
