If a client chooses to make a new feature via DVM, then other clients could adopt the feature quickly.

Consider recommending new people to follow on Nostr. Each client could implement their own version, or instead one person could make a DVM that other clients hit to get the data.

DVMs may cost money but paying per each request to the DVM probably doesn’t always make sense. “Salaried” DVMs might be a solution.

Client subscription fees could cover DVM fees. Free clients wouldn’t have the paid DVM features.

Network effects would be insane here!
