A very common complaint I receive about the comment rating system is that people accidentally hit the wrong button—resulting in a plus where they intended a minus, or vice versa.

So now, after clicking the plus or minus button, the opposite button will still be active and clicking it will reverse your rating. And then all’s right with the world.

UPDATE at 9/7/08 3:48:19 pm:

Ratings for front page posts (like this one) are also now reversible.
