It's too early to tell for me. My mvp proof-of-concept was front page on HN and has had a ton of signups, but the manual payment process I'm using really sucks and no one has actually paid yet.
I'm currently writing the automated backend to enforce payment (along with some improvements), and then we'll see how much revenue it brings in.
