Not sure how it works, but I guess you could do both ๐
Zaps have economic value which I agree with. In my mind, zaps works like it does here on Nostr but at the same time zaps boosts a review which then jumps up. The more zaps you get on your review the higher up it comes and becomes more noticable. On the other side, this all depends on how a person use reviews. Ex q: are you the person who writes a review and hope for it to be seen?, or are you the person who uses reviews to find for example a good restaurant, museum etc? (Which I do). This all comes down to user experience and if zaps would be of value in positive way.
