Putting yourself out there for one. Sites like this help a lot, given the niche community.
But it's a lot like anything else when looking for a relationship, whether that be platonic or romantic. You strive to find a community and seek out like minded people.
Be communicative and make sure you're both on the same page about what you want. However that sort of thing takes time in order to establish a meaningful connection.
SlyFox:
Thank you so much! These are very helpful pointers
Mobius:
Hopefully that helps.
Also, and I am sure you know this. But bears saying, sometimes it can be really exciting to find someone local. Like any sort of situation exercise caution and discernment with meeting up.
All of this is good advice. But I also want to add be a good conversationalist. You can be the nicest person in the world, but if you can't carry on a conversation, the other person won't want to stick around.
