I'm really wondering!?
I go into work blissfully unaware of the FaceAche stuff and have to actually converse with people who have shared all sorts of shite the minutiae of their life on FaceAche.
I then have no idea what they are on about.
But frankly it's usually a lot of pish anyway - but it's not very inclusive IFYSWIM?
Other colleagues come in and do all the "Ooh, I saw your photo, blah, blah blah" and I'm standing there saying "What are you talking about?" in a grumpy tone.
