@JThorne Very few communities survive with few users. A social network's primary function is to help you connect with others, something you can only do if there are others to connect with. And it just so happens that our relationship graph is not a circle, people have different friends with different interests. Network effects: a network survives and thrives if there are lots of users, as many as possible. That's why you try to appeal to as many users as possible, to everyone.
