Why bother adding event descriptions in Amplitude? Anuj Sharma, Sr. Customer Success Architect here at Amplitude, explains:

“Descriptions make it really easy to understand what that event is for. If there's a new user who's onboarding to Amplitude, onboarding to your taxonomy, descriptions make it a lot easier for them to follow along and understand what that event really means. So you should definitely add descriptions to your event, event properties, user properties, and make it available, in your event dictionary within Amplitude, wherever possible.
