In which circles is this the case? I know personally many people who don't have any "posts" in any meaningful way or quantity, and a number of ones that don't have any presence on social networks. Then there are a lot of other people who technically have presense there, but just in a way that they have an account - not in a way of using it or logging into it.

It is also strange to hear that if you have a landlord who is weird by asking for facebook account - that the assumption is that it's Mark Zuckerberg's fault? Shouldn't you blame the landlord for that?
