 Replying to [comment:1 mdawaffe]:
 > What's the value in allowing reverse diffs?

 I can't think of any, but the current UI gives you the impression that you
 can do it.

 > With the current UI for the diffs, left is always older, right in always
 newer, red is always removed, and green is always added.  Allowing reverse
 diffs takes away that consistency.

 OK, agreed.

 > How do you see a one column of radio buttons UI working out?

 You just have the one column of radios, and you select the two that you
 want to compare.  It's straightforward.  We could even leave in Matt's
 easter egg for the case in which someone just has one radio checked.

 > We could do it the way mediawiki does it: two columns of radio buttons,
 but only show the ones that are "legal".  Click around on the radio
 buttons http://en.wikipedia.org/w/index.php?title=Main_Page&action=history
 to see what I mean.

 That's fine, too, but just involves more work. And if it's like
 MediaWiki's Matt's easter egg won't be possible.  :-)
