I think it always came up on the old style news feeds anyway didn't it? Think you can select who it displays to though; if you hover over the right top hand corner of your post it comes up with a little drop down menu where you can choose. And yeah agree with the 'urrgh'! I don't even have that feed thing and tried to send an error report but it kept saying I hadn't filled in a section that I clearly had!
I think there must be a default setting somehwere as all of mine so far have been to display to friends only without me having to do anything. No idea where that would be though!
Have just found it! Click the little arrow next to 'Home' at the top right hand corner. Then go to 'Privacy Settings' the first thing on the page is 'Control Your Default Privacy' that will probably do it but with Facebook you never know!
