Thanks, enjoyed it very much!

It may be a silly idea but on the topic of finding an audience or interests or whatever..

Perhaps when you've installed a client and you're just getting started with your new npub, a setup could ask if the user has any interests they'd like to see on their feed. If the user says "Art nouveau" for example, it would add this as a tag they now follow, or perhaps even populsr npubs that use this tag. The setup should also mention how to manually follow tags.

I don't know if this is feasible as I'm not a dev so I'm just putting it out there.
