Now the current pattern for the Acceptance rate is having a percentage and a color. Green being the most acceptance rate and red or ash for the worst acceptance rates.
How about adding a seal for say 98% or above acceptance rate for a minimum of 20 questions asked. And probably a seal can be showed prefereably in the card or somewhere catchy with a custom image something similar to this.
The objective is to make it Crystal clearly visible and thus encourage people to eagerly answer for people who have high acceptance rates faster than it is right now.
