I think the best way to make friends is to become part of a community. You could try joining in the conversations on the dance floor at a club that has a good crowd, say like Big Daddy's 80's club and Wet Willies Rock club, both of which are busy 24/7, or by joining a group like the RP groups or now days there are a lot of Motorcycle Clubs in world. These communities can be a little tough to crack, some are harsh on new people but if you stick with it you can usually make a friend or two that will last the distance. It is about putting in a little effort though, having something to say, messaging people in a friendly manner and having a discussion and stuff
