While trying to reproduce the bug posted here, I noticed something peculiar.
When you completed a review of a post, your name shows up on top for other people to see.
I'm not sure how I feel about this. When I edit an item I reviewed, my name is added to the question or answer for obvious reasons. However, I expect reading, reviewing and voting to be completely anonymous.
I don't really see the added value of having this information, and to me it raises some minor privacy concerns.
