meetup.com offers a large collection of interest groups to join. It probably is less useful for low density areas, and I don't know if they operate outside the US. If you live in a large urban area (I'm in Austin) there are literally hundreds of meetup topics. Knitting? Music? Hiking? Books? Psychedelics? Religion? Sports? Investing? Meditation? Learning a language?
There is no guarantee that you'll make a friend there, but the odds are much higher than watching TV at home.
