You know when you scroll down and it looks like you haven't posted that much and what you have posted has been very much liked and commented?
Turns out facebook is a sneaky fucker. Click on timeline month by month, or click Activity Log and you will see all the useless shite you have posted, and forgotten about, and is still lurking on facebook, popping up on the side of your mates feeds and all sorts, and being used for who knows what algorythmic data by the thing.
Just went and basically deleted everything other than friend's comments up until recently. SO MUCH SHITE.
