I would not object to a customized ad feed that I can access or not based on what I'm looking for. It would take all of my notes and replies, and allow me to put in a search parameter, and would come out with specific recommendations for products and services that it thinks I might be interested in. Then I can choose to buy those products and services and move on with my day. But the second those ads or algorithms start showing up in my main feed, I will mute that npub trying to push/pull content and I'll never have to deal with it again.

If I'm in the market looking for something, show me that thing. If I'm not in the market looking, get out of my face.
