I was recently invited to the new Embedded Systems beta and I noticed that I could click on the vote number of a question or answer and it would show me the breakdown of up votes versus down votes. I thought this was pretty cool and mentioned to a friend that I wished the EE.SE could do that too... To which he replied that it did.
So, I guess my question is: What is the rule/pattern for being able to view the up/down vote breakdown for a question or answer?
It doesn't seem to simply be rep based because I have 101 rep on Embedded Systems and I can see the breakdown... but I have 560 rep on Electrical Engineering and cannot see it.
