Could people please give me some information on how javascript affects loading time for someone on a slower computer? *dunno*
Anyhow, I'm not too fussed over the matter. If the admins are fine with your use of javascript, I don't give a damn, I guess. But in that case, I don't give a damn about anyone's use of javascript, so long as it doesn't do what Bleys mentioned earlier.
EDIT: Why did bennator0's javascript bother you, out of curiosity? That could have something to do with why it's not allowed.
