The above fixes address the most critical css layout bugs, though I or someone should still go through other parts of the site (e.g. diary, user contributions...) and see what other fixes are needed.

In the longer run, there likely are better approaches than this patch, such as a separate ___-rtl.css file and maybe using sass (e.g. http://amitkazmirsky.com/2011/05/29/dry-your-rtl-and-ltr-css-files-in-rails-with-sass/) or something to handle flipping layout elements. I'm willing to help work on this.

SASS doesn't appear until rails 3.1 IIRC and we're still on 2 so that is probably out for now but I'll have a look at the CSS changes you propose later.

I applied your patch, reworked it to move the LTR/RTL stuff into separate files as you suggested and then fixed up a ton of other broken things. It should all be live shortly.
