Okay, not so much the use of the CSS @import rule as much as the mechanism used to deploy the rules. I haven't seen a lot of user installable stylesheets that "phone home." Seems like an under-utilized technique.<p>UPDATED: Yes, I understand @import is used frequently on the web. My point being A) You don't see a lot of <i>browser-installed</i> stylesheets and B) the few that I've seen haven't made use of @import.
