A social networking site is what you make of it. But if you have public material that is easily searchable, people are likely to judge the content they see. Not that this is relevant to the OP, but since you asked:

I think most people would agree that your instagram page has some extremely materialistic pictures. You tagged the rolex pic with the line "#money #suits #rolex #rkoi" (rkoi = rich kids of instagram).. I would look into making those pics private, because to many people outside your friend group, they come off as super douchey.
