The thing is that for the more niche kink communities on Tumblr the fact that everyone was using it was what made them work.

You will never get that kind of activity on a Tor service. If you look at the more obscure, older fetish-related networks which often still have active IRC channels and such you'll notice that a large portion of people there are quite techy.

I don't think that's true for the wider kink community at all, it's just that the barrier of entry & discoverability of such communities will exclude the less techy folks.

I agree. If something isn't happy-clicky and already works from their existing browser, most won't bother. Perhaps you could develop a simple innovative way to make Tor easy for that community to adopt. Maybe a small number of them try it out at first.
