I think this can be gamed somewhat. Fiat world really likes metrics of popularity, but on Nostr because of relay sync issues you can never truly know how many views you had. However you can know how many total zaps and zap amounts through tools like Zapalytics. With sats being so cheap, it may be feasible to encourage users to zap even just one or two sats at a time to show their support. It gets them to put their money where their mouth is in an almost literal sense, and when they have to top off their nostr wallets they are encouraged to think about what was it they liked that was really valuable. It at least can help nudge them in the right direction if done properly.
