Well, depending on what interests you, what you'd want to talk about; I'd take a course or join a group that included that subject matter and then everyone would be "interested" and/or you'd have a great "reason" to talk to someone and/or invite people out for coffee/drink, whatever afterwards, etc. to explore other subjects. It's good to have a core identity to be able to work from, like moths all flying around the same light, LOL
