I have an implementation idea for you:

Create a service that scans and collects the bookmarks of all users and analyzes them. Provide top lists and similar insights. Then sell the results for Sats. You can tier the prices based on the number of analyzed users. Advertisers are extremely interested in such data, as bookmarks are the most honest metric. However, keep the users anonymous; otherwise, you'll face backlash. 

 Thanks, will look into it
