Is there any way for me to see how many upvotes and downvotes I have in a given tag? I am working toward having two tag badges and would like to know how far from my aim I am.
You can check the user stats page for that tag if you are in the Top 20. The light grey number is how many upvotes.
Remember the scope you are looking at. One column is just the upvotes for past 30 days, the other is all time.
If you aren't on that page, I don't believe there is one.
Your user page now shows your score per tag, under the tags section. Mouse over the number to get a detailed breakdown.
I've also posted a report online here that shows a number of stats, including upvotes and downvotes, for each user and tag. Currently I've only run that query for users with over 20k reputation, so unfortunately it doesn't show your account. But hopefully this will be useful for others. :)
There is also a greasemonkey script that will fetch your tag stats for you:
