Considering the negative effects of document.write(), why are most tracking/marketing tags written using document.write()?
I've thought about it quite a bit, and the only respectable idea I've come up with is that by writing it client side, we're guaranteed the browser won't try to cache the resource. Is that it? Any other ideas?
