I think the only thing I will miss is exactly this. Being as enormous as Reddit is, any tiny niche thing would be, although tiny compared to the total userbase, gigantic compared to what any other site could provide. That's 100% of what I will miss. I don't think I will miss anything else.

Taking that into account, I realized there are other sites I can access these niches. And I realized that, knowing this, I have nothing else tying me there except the "ease" with which I will find this stuff. And even then, social media is changing. I can find info on stuff like this on Discord and other such places. Even Reddit can be way slower than many of the modern tools we have.
