For me, this is the strongest case yet for niche social networks being the future of social media. FB is too broad and demographics tell you little about the people you are speaking too unless you can inject some sort of context. If (via a Distributed Social Networking Protocol) people were subscribed to several social networks focused on their hobbies and interests, then I believe Social Media Advertising would be more viable, and more useful to the audience. You don't need DSNP: niche social networks already exist. Ravelry and GoodReads, as examples, seem to be making a decent go of it. Would love to know how their advertising does.
