I was reading the close dialog on a question that I had already voted to close. I put my cursor over the vote count and saw in the title attribute text: "these many votes already exist". Shouldn't this be "this many votes..."?
No idea when this changed, but as of April 2016 that tooltip reads 'number of votes already cast', which feels like a slightly more grammatical description.
I feel it could probably still be improved a bit, but the current status is fine.
