Whenever someone say this line, I ask them how would they go on to define "B player". Most would think they intuitively know this but I've rarely seen people actually able to crystallize this effectively. In fact, when people actually put an effort to define this it would quickly become apparent how badly they have misunderstood this fundamental. I've some thoughts on this but I rather not bias HN crowd here :). But here's the hint: 1. B player is not someone who doesn't know X. 2. B player is also not someone who said in their resume that they know X but they actually didn't knew X all that well. Now your turn!
