Very cool stuff! I'm going to be using it personally. Thanks for the hack!

If there will be another version, here's what I hope will be in there (minor things, not really necessary):

• Layout of + and - votes looks more like the layout of what's shown to 1000+ rep members (slight css change)
• Making this into a Firefox plugin or a Chrome extension so it does it automatically (not sure about Firefox plugins, but with Chrome extensions, it's a piece of cake.)
• As this uses jQuery anyway, once the function is executed, the up/down vote counts are loaded into the background and click handlers are added to the total vote counts, so that it really resembles the experience that 1000+ rep users have.

As it's under WTFPL, I'll try to implement those features myself and post my results.

Thanks again!

UPDATE: I started making a Greasemonkey version of this; here's what I have so far (I don't have too much experience with GM, so I'm not sure whether this code will work):
