I depends what your interests are, but there's almost always a channel on one of many IRC networks for any topic. Channels might not always be huge, but a lot of subjects have 30+ people. Non-/r/All subs on reddit can also be great. Through these you can usually find another message board, chat, etc with another community (often the same people and then some.) Often when I'm looking for a community that is focused on a specific topic, I search a common, but specific question for that community. People often say that IRC is dead, but its not -- and it doesn't have to be. Find a channel and get talking. When the next searcher stumbles into the channel, welcome them.. repeat. Before you know it your channel of five or ten is up to 30, then 50. Ultimately, it takes a night of tumbling down a rabbit hole. I can confidently say that there will be at least one thriving community filled with people with your similar interests. It just takes some digging beyond a search engine alone.
