With just an ETag set , anytime a repeat visitor hits a page with a static asset already cached, it will send a INM request, and the server will respond with a 304. If you have just the expires or max-age set, the browser won't even re-validate the object, it will just serve from the browser cache, saving on some bandwidth. I don't think adding public to cache-control would affect anything either as that IIRC just makes http authenticated responses cachable.

Most browsers interpret it as "Cache-control: must-revalidate" no matter what other headers you sent with. In fact, I've just tested twitter.com on my Firefox 3.0.7 and the CSS files don't even seem to be cached at all. The culprit here must be the Vary header.

Proper timestamps for assets would probably save them more than a lunch in data transfer fees :) They could at least use Amazon’s CloudFront as a CDN which is so easy to implement.
