You can save traffic if you compress your images better. You could probably optimize them for better results, but even a plain "optipng -o7 *.png" for the frontpage stripped away about 180 Kilobytes.

Also comsider using JPEG for some images, it might be much smaller. Using a small palette and no transparency is the key for small PNG.

Site optimization took a back seat so we could launch it early. I'm generally a stickler about sprites and whatnot - none of which are used on the site. JS and css is combo'ed and minified but that's all.

optipng would be an easy fix though and will try to do that for the next release.

Thanks for the feedback.
