Q:

Why cannot I see the breakdown of + and - votes on Stack Overflow like I can on Programmers?

What happened to the up/down vote count (vote details)? 

When I am on Programmers, I can click on the vote and see how many ups and downs there are. Why cannot I do this on Stack Overflow?

A:

It's because you don't have 1,000 reputation on Stack Overflow.
Check the privileges page for what abilities you get at what reputation level.
These are consistent for all graduated sites. The reputation levels on beta sites are lower and on private beta lower still.
