Most social sites advertise how, through connection to others who share the same interests as yourself, it is possible to grow your network, enhance online experiences, share knowledge and so on.
Could this be the wrong approach?
While there is no doubt you can meet like minded people, it could be argued that access to new information, thoughts and increased awareness would come from exposure to those who do not share your interests.
The question of relevance exists, but still, just a thought.
