A day or two ago, I was able to see upvote- and downvote-counts here on meta. That Feature is gone now.
Was it a bug that it was available or is it a bug that it is missing now?
The reputation required to enable different privilege (such as viewing vote counts) increases when the site moves from private beta to public beta. It now requires 750 reputation to see vote counts, both on the main site and here on meta. It previously required only 100.
You can see the full list of reputation requirements at different stages in this post on Meta Stack Overflow.
