Thanks! @Stephanie: Stylesheets aren't as bad as external scripts. Scripts block other downloads (in many browsers) and also block rendering. Stylesheets only block rendering. Either way, it's probably a little faster to avoid the DNS lookup even if you pay the price of cookies, but it depends on how big the cookies are. I would reserve the same domain for scripts, and shard stylesheets on a separate domain. It's also more important to keep scripts on the same domain for XHR (so you don't bump into the cross-site security restrictions). @Jan: I fixed the “slides” link. Thanks!

Putting it on a cookieless server forces another DNS lookup. Shouldn't we treat it like an early loaded javascript and put it on the same server, even if that implies serving it with a cookie?
