Great post! Thanks for sharing.

One point I’d like to know more about is the choice of using “defined user answers”, instead of letting users to write their response. 
Assuming that free writing is the most natural way to use a conversational UI (messaging, chat, etc), I wonder if this could affect the user experience.

A single golf clap? Or a long standing ovation?

By clapping more or less, you can signal to us which stories really stand out.
