Looking at a timeline view, I'd like to understand what people were looking at when votes were cast.
The votes themselves should be anonymous with respect to who voted, but upvotes, downvotes, and bookmarks should show up in the timeline. In addition, a person undoing a vote should also show up. They should show up with respect to when they happened with other events, such as edits.
There is a way to see daily vote summaries that, once a day, display the number of upvotes, downvotes, and bookmarks. However, this doesn't let someone understand the state of a post when the vote was cast.
