marking a comment up or down should use ajax- especially so browser history is preserved (pressing the back-button to get to the front page). I assume comments can be marked into the negative range for those hopefully rare occasions where it's needed? [please don't test it on me!]. Other than that I love the minimalism.
What about a separate feature requests page for those that already have been accepted and implemented like this one? And maybe another for formal rejections.
I think it can get confusing reading suggestions for features that have been implemented since the request was made for less obvious features than ajax voting. And they're not particularly relevant anymore. Of course I wouldn't simply delete them so a separate page would be a good compromise.
I agree with this suggestion, but for another reason. There have been a few times when I'm writing a reply and I stop to think for a moment. Occasionally, during this pause, I will glance up and notice that I haven't voted the article up yet. Unfortunately, when I do vote the article up, everything I have written up to that point gets cleared. I have tried pressing the back button, but it tends to take me back to where I was before I started writing my comment.
I understand that this is an error on my part, but that doesn't alter how frustrating it can be.
that doesn't solve the problem that I (and I assume others) habitually press the back button when I'm done perusing comments in order to get to the main page. At this point when I press the back button it goes to a slightly older version of the comments page- and various other oddities.
I run into this problem all the time--not good for diminishing by reload-addiction! It would be nice if pages included some js to rewrite history via dom, so that we could always see the freshest versions of pages.
 It pains me to advocate breaking the "show me exactly what I was just seeing" semantics of the back button, but I think in this case the user clearly conceives the back button as "show me the abstract resource I was just seeing."
