I know anecdote doesn’t mean data, but I met my wife on OKCupid. We’re both asexual trans women, and the notion of finding someone so compatible like that would have been terrible had we done it in real life, locally only. She was in Boston, I was in Portland. And asexual trans women are a minority of a minority, so it would have taken forever in real life.
Then again, OK Cupid has since enshittified.
Too late, already married!
