I run a site for people learning Japanese (https://jpdb.io) as a side project. I'm currently at exactly ~$1996/month from Patreon donations. (It's not an aggressively monetized project.)
I've been doing this for over 2 years now. You can take a look at my changelog to see most of the updates (at the beginning I did not maintain a changelog so it doesn't start exactly when I started the site): https://jpdb.io/changelog
