i'm looking for software or websites where i can enter my interests (in my case for example: buddhism, astronomy, psychology) and find other people with similar interests
(The location doesn't matter, i'm not looking to connect with people locally, but rather online. Also the site itself does not need to have a chat feature, just contact info)
What i'm looking for could be a software or website with a recommendation engine similar to getting movie recommendations, but the software or website could also be much simpler by just matching by interests. (I'm also open to other approaches if there are alternatives)
Grateful for help and with kind regards, Tord
