>>38776967Speculative Biology and Chuubanite are the most common ways most nations that dont have much to do with one another get introduced to each other, like how the Salamansho Rex MonHun got Vnug, the Candy Kingdom, and Moriji to interact for a single political goal and acts a waypoint for future political endeavors. There's also the whole synthesis aspect of chuubanitewhich gets collaborations from different nations to see what might happen from similar concepts like with /meat/ and the flesh jukebox, if those don't interest you that's fine but in the same vein they open up to potential discussions outside those topics.
>>38777111I generally don't expect an interest to occur for someone that doesn't really have a reason to pay attention to someone elses culture unless the idea is very public and gets eyes on them. I think the solution to that might just be to post a bit about the idea before you put it into a rentry for it to get more exposure to anyone interested in it or might like it beforehand which used to be commonplace.
