That's retarded. People need to see reactions...its a social network..people leave Nostr because of the current lack of engagement
Go for one month without using likes/reactions at all on nostr and see how your behavior and engagement with others changes. Then make up your mind about the value of likes.

Not to mention zaps break constantly
What do you mean?
My wallet will either: not send zaps at all or double send zaps. Either case causes unnecessary friction to social engagement.
Aside from that, an emoji reaction conveys some meaning, a zap conveys value.
A double spend in an interesting issue, which wallet are you using?
A reaction tells me nothing, they are broken because I am not a social media platform mining data.
See reactions dont even show. 
Mutiny wallet, hasn't been great thinking about moving back to Phoenix.
You can opt out, it doesn't change that 🤔 means something different from ❤️ or 💪🏻.
Emoji reactions convey differences in kind, zaps only convey differences in degree.
