Step one is hard. Some way of meeting people with whom I share peculiar mutual interests, but not peculiar mutual friends, is hard.

Instead of a social networking app that tells me, "These are your friends, we'll help you keep in touch", I want an app that says, "These are people that might be your friends". The current social networking applications do a good job of telling me all about my current friends, and allowing me to keep in touch in a passive way. The issue is, most people have a hard time meeting new people after college.
