This is awesome, you seem to be in touch with what your users want and then work to deliver it (whereas with many side projects I see it's more the developer building exactly what they want). I wish you much success!
These days I am doing my best to know what users want, but it gets harder and harder. Previously I could talk to 1-2 users and already get a lot of insight. Nowadays there are often conflicting requests or just too many of them. I think this is the price of growth. Still didn't figure out how to scale this well. The stats are public, by the way, https://firedating.me/open/ :)
I wouldn't call it 'advertising', but I do mention it in FIRE subreddits every now and then. r/financialindependence is (understandably) super strict about self promotion, but the existing users mention the site in comments there. Thank you!
