Today's Parola del Giorno is the noun la bacheca, which means bulletin board.

When Facebook first debuted, the place where people shared photos and updates was a called a wall, a virtual bulletin board where users posted updates to their status along with pictures and later videos.  

See the noun used below:

Odio la bacheca di Marco perché usa Facebook solo per giocare: Farmville, Cafe World, Cityville.  La sua pagina non è molto interessante e non mi piace vedere questi aggiornamenti fra gli stati.

I hate Marco's wall because he uses Facebook only for playing games:  Farmville, Cafe World, Cityville.  His page is not very interesting, and I don't like to see these updates among the statuses.

Of course, Facebook has changed a lot over the last decade!
