I quite like the new alterations. I won't go into committee mode and start nit-picking but I will talk about;
* Rounded Corners
I like the idea a lot. It's very 2.0 and stuff. I appreciate the hard work you put into your http://theinterference.com/, no images version. However standards support and XHTML is about *removing* as much non semantic markup as possible. I don't think that a core drupal theme should be putting in 10+ extra divs per rounded box. It is not the correct approach for a site that claims any kind of accessibility. Taking advantage of the jQuery plugin is a good approach, however it does not alias (pointed out) and it takes a fraction of a second to work, resulting in a flash of squareness (nit-picking). It also seems hackish to me and will not work if javascript is disabled, and/or old. The only approach I've seen that uses the minimum of extra markup, allows any kind of corners (aliased?) and uses the least number of images is the sliding doors technique. Just some thoughts.
