There are a few people in particular I have on facebook who are class A socio-paths... they can't even just post a picture of something kind of awesome and let the picture do the talking, it has to be accompanied by a caption saying something like "Work just gave me this flashy Merc to drive, ain't nothin "... and the same people do that annoying thing of putting up some willy-waving photo, wait a few weeks while all the sheeple "like" it... and then tag themselves in it, popping it back to the top of the news-wall thing for everyone to see all over again... Or post a status and then comment on it themselves a week later... RAAAH just **** off already!
The other day someone I know posted a picture of the food they were having with their family. I was just visualing it, "hold on guys... I have to take a photo of this... now uploading it to FB... with a comment..." And then he carries on checking for likes and comments throughout the meal. How about spending the time properly with the people who are there?
