Here are a few things that come to mind that may help!

Getting sustainable/consistent income:
1. Have a dialogue that pops up once after installation, that allows users to opt-in to zap-splits, so that every time someone zaps a post, Damus gets a %
2. A "Damus+"/"Damus Pro" etc paid subscription tier with extra features
3. Turn amazon/walmart/etc links in posts into referral links, and have that be opt-in of course.
