There are people (you know who you are) who are on a mission to get as many Facebook friends as they can. But if you've taken to updating your pals with the smallest detail of your life, you could lose more than you gain.

According to a new study, Facebook addicts are the most likely to be "defriended", thanks to their continuous status updates detailing the minutiae of their lives.
In fact, being boring is the number one Facebook crime, say the researchers, and the top reason for going back on the 'friend' agreement.
The news comes courtesy of researchers at the University of Colorado who analysed 1,500 Facebook accounts to find the number one reason for defriending, where someone decides to delete someone from their online buddy list.
Following downright dullness was a constant flow of updates, crude or rude language and talking about politics or religion.
Of those who removed a Facebook friend, only 27 per cent did so because of a real world disagreement, compared to 57 per cent who deleted a pal for something that happened online.
Christopher Sibona, from the University of Colorado, had this advice for the frequent Facebook user: "The 100th post about your favourite band is no longer interesting.
"Another reason was posting about polarising topics like religions and politics," he told the Daily Mail. "They say not to talk about religion or politics at office parties and the same thing is true online."
And addicts be warned - it's not just your pals who could take your updates the wrong way.
Apparently prospective employers are increasingly turning to Facebook to find out a little bit more about potential employees.
Dr Sibona added: "The same kinds of posts that could get you unfriended might also be viewed negatively by recruiters."
So updating the world on your latest wild and drunken night out might not be the best idea.
