There is a big difference between "I'm polishing this because it will have a higher viral coefficient", or "I'm polishing this because I am learning by polishing", or even "I'm polishing this because it feels good to polish" on the one hand and "I'm polishing this because I'm afraid of the feedback I'm going to get on it once it's in the wild" on the other. My polishing falls more often in the latter camp so I look for ways to counteract my bias. If your polishing really really makes a difference, then heavens to betsy be my guest.
