Yes, I think you're right that indirect reach is helping here. A couple of the subscribers that I have gotten have very large (100,000+) readership. I've also re-stacked a couple of articles that I really like, with notes about why I liked them, or had comments on articles that have been re-stacked by the writer. Network effects are definitely at play, but since I can't have any impact on that directly, I'm just trying to engage in the most thoughtful way to everything I encounter. Also, I love speculative fiction and just subscribed to your Substack! So I guess you kind of got a new subscriber via Notes (in a roundabout way) :)
